Q:

I am looking at a manual sharpener what would you recommend?

Answer: Get yourself a Worksharp knife sharpener, either the orig one for $60, or the updated Ken Onion edition ($120), both are FANTASTIC. I’m TERRIBLE at sharpening anything, but this thing (I got the Ken Onion edition) has made it easy, quick and best of all, a “good knife sharpener” out of me! I don’t sell them, have no affiliation... I just like a good product when I get one, which is rare these days. Good luck.

Answer: I recommend going to your local harbor freight or ordering online and getting a 1x30 inch belt sander and getting some 600 grit bolts and a leather polishing belt for the sander too and you will have razor sharp knives all the time. Dont waste money on a work sharp. You can get the harbor freight set up and the belts for about the same price if not cheaper

Answer: Hi there,

Answer: Get a Norton crystolon or India stone and learn to free hand. You can get either for probably twenty online or in a hardware store.

Answer: This is a knife. If you need a sharpener I recommend asking the question on a sharpener listing. Good luck.

Answer: I use a 2000 grit stone. Great knife for the money.

Q:

How well does this hold a edge? Also after a couple sharpening does it still hold a edge like if it was new?

Answer: For those too young to remember great grandpa shaving with a straight razor, let me give you a quick education. RAZOR sharp knife means it will not hold an edge. The sharper the edge, the quicker it will dull. That's why great grandpa had a razor strop that he honed his beard cutting steel with every time he used it. A fine razor edge on a fillet knife is important, as is the knowledge that you must hone (not sharpen) the edge regularly to maintain it.

Answer: Gets real sharp when sharpened but Won't hold an edge for long. Even the guy at the knife sharpening store said it was a very soft blade. Not recommended for everyday use.

Answer: It does not....

Answer: Not for long.

Q:

What would be the best sharpening tool for this knife?

Answer: This is a large can of worms on this ask; I ask 10 folks, will get 10 answers. Since I was little, was taught to use an Arkansas stone, it's my comfort zone and haven't met a blade I couldn't hone yet. I've tried other methods, but for me, the stone is far superior. Technique and angle are critical no matter what your chosen poison for sharpening, practice, practice, practice.

Q:

Can a lefty use this knife or is the blade made for right handers?

Answer: I am also a lefty. It works well. Really solid knife for larger fish.

Q:

What is this knife's Rockwell Hardness? (please answer only if you know)

Q:

How does this knife do cutting through bones?

Answer: I wouldn't use it to cut through bones. That would ruin your knife. This is meant to cut meat away from the bone.

Answer: not sure any knife will cut bone

Answer: Went through rib & y bones in a salmon very easily.

Answer: It will cut through, but dull the blade after a few fish. It’s easy to sharpen after

Q:

Do the knives come sharpened out of the box? I see a number of complaints about dull blades.

Answer: I've always used the rapala's. I read the same as you but I still ordered. The knife has a nice non slip handle and mine came very sharp! Also in the box if you fill out a questionnaire you receive another knife or sharpener free of charge. Great deal now I have two!

Answer: It comes factory sharpened which is certainly adequate, but you’ll need to run it over with a sharpening steel to get a razors edge.

Answer: Hi Stewart,

Q:

Do these knives contain lead?

Answer: Hi Will,

Answer: Hi, it says it's made of stainless steel. however, when googling if stainless steel contains led it gives a varying of answers. Many of my Culinary friends use this product and we haven't head anything negatively from the teachers! I hope this helps..

Answer: The blade is lead impregnated. Cal Prop 65 approved! It holds a hella sharp edge.

Answer: No I don't believe they do. But what I will tell you is their built very well. Really sharp top. the only set back for me is .. Personally I like knife sheath that hang from the belt. And this one is designed for your belt to go þrough the body of the sheath. If you know what I mean. But ovèall I like it very much, and I feel like it's perfect for fishing, which is why I chose it. Made very well and definitely worth the price tag. thx

Q:

Is it dishwasher safe? Knife and sheath?

Q:

Does this knife really come sharpened?

Answer: It comes sharpened, but I touched it up before filleting fish. I like them sharp enough to shave and they are not quite that sharp. I cleaned a mess of catfish yesterday and they worked really well. I have 3 of these knives. The strong and the fillet in 9" and have the bait knife

Answer: My carving knife was “sharpened” but I’ve seen plenty of other sharper knives.

Answer: Hi Drew,

Q:

Would the 12’ slicing knife be good for carving a turkey?

Answer: Hi there,

Answer: I’ve only cut my brisket with it so far but plan to use it on my turkey this Thanksgiving. It does a great job on beef.

Answer: I believe so. It’s worked great for me on briskets, ribs, steak, chops and chicken.

Answer: Yea it would.

Answer: Absolutely !

Q:

How do you sharpen this knife?

Answer: with any standard knife sharpener. Amazon has plenty of options

Answer: Not sure. I usually take my knives to a professional knife sharpening service.

Q:

how well will the knife do against salt water? Will it rust, or corrode easy? I am an saltwater angler. Also how long is the whole knife

Answer: The knife appears to be quality made. It is described as "German Stainless Steel" so I would say with reasonable care it should hold up. No knife or any metal object for that matter will resist rust in salt water conditions without proper care.

Answer: It will rust like most steel in saltwater. This will be best avoided by rinsing off with fresh water and hit it with a little WD40 after every trip.

Answer: This knife is junk - period.

Q:

I'm confused on the differing reviews on this knife's ability to maintain its sharp edge. Does it stay sharp or not?

Answer: As with just about any knife you get, you’ll have to sharpen it after processing a few fish, especially if you are cutting through scales and/or bones. But you only need a few swipes across a sharpener, and it’s good to go! I found that it remained sharp through processing about 7-8 Alaskan Salmon (cutting scales and bones), before I needed to tune up the edge with a sharpener. Hope this helps!

Answer: It keeps its edge pretty good compared to other filet knives I’ve owned. It’s a good knife, but eventually it does need to be sharpened.

Q:

Does the sheath have a belt loop?

Answer: No it doesn’t

Answer: No it does not

Q:

Is it full tang?

Answer: Hard to tell with soft handle, but it seems like metal runs through it

Q:

Could i debone a chicken with it?

Answer: You can debone anything with this awesome knife. I’ve only had it a bit but I’ve used it on deer and hogs and even fish

Answer: Not really it’s great to fillet a fish but too wide to debone a chicken...

Answer: While we advertise these knives for outdoors, we have had many people use them in the kitchen. They are great universal knives.

Q:

Does the size include the handle or the size of the blade?

Answer: Blade size.

Q:

Would the 12 inch slicing knife work well to cut through brisket and slice up ribs?

Answer: Yes it would work great for that

Q:

Can this knife cut hard organs?

Answer: Not sure what you mean by hard organs, but the knife does cut through, skin, muscle, tendons and other tissue very easily.

Q:

Would the 12’ slicing knife be good for carving a turkey?

Answer: Hi there,

Answer: I’ve only cut my brisket with it so far but plan to use it on my turkey this Thanksgiving. It does a great job on beef.

Answer: I believe so. It’s worked great for me on briskets, ribs, steak, chops and chicken.

Q:

how does this work on 3 pound catfish?

Answer: I only use it for skinning deer and elk, but it is a good knife and I would think it would work well for catfish.

Answer: Should have no problems! Works on 5Lb walleye.

Answer: Depending on the size of knife you choose these things can handle a 3oz crappie to a 350 lb shark... I got tge small bait knife its beoynd razor sharp out the box... Get one qill make skinning and fileting your kittys a cake walk

Q:

Which one is better this kastking g4116 or kastking white 8cr14

Q:

Is this made in garbage China?

Answer: Probably lol it’s a nice knife though, feels good in your hand awesome on 27inch drum and smaller fish

Answer: Probably half of what you think is made in America that you consider quality is made in China by American manufacturers that outsource parts. China has pretty good technology because they stole it from everyone else. Might as well take advantage of our own tech from time to time. If you find something comparable made here or in Europe, go for it.

Answer: I dont know if it is .. but I will tell you I dont think there is any way you could find a better knife for the price. We use it now on a regular basis on our boat in saltwater and had NO issues with it .. and its super sharp out of the box ... I think the key to most knives is to have them properly sharpened .. most people dont know how to and ruin the edge and then blame the knife ... I am buying a couple more as gifts .

Q:

Are these knifes Dishwasher safe?

Answer: Hi there,

Answer: Yes, but you shouldn’t run knives through the dishwasher. The heat softens the blade over time.

Answer: I'm not sure but I suspect they are since I've washed them (I have several) in hot, soapy water after letting them soak with no problem.

Q:

Does anyone have the offer code for the free item? Mine was thrown out when my wife was cleaning up. Thank you!

Answer: Nooe

Q:

Should I get the finesse version of the blade if for filleting fish usually 5 pounds or less? Finesse, regular, strong.

Q:

How's the backbone on this knife, stiff, flexible, or in between? I saw one review calling it in between I guess, do I have a second or a third?

Answer: Yeah In between is a good description for the knife. Great knife love it. Got to use it on some flounder and reds this fall and it did great

Q:

Will the 6 inch knife be good for trout up to 12 inches?

Answer: I think this knife would be fine. The blade length doesn't need to equal the length of the fish if you only intend to use it to clean and gut trout. I've used a pocket knife in a pinch, but you won't want to put that back in your pocket.

Answer: After using this 6 inch blade on smaller trout. I will be getting a 4 inch blade.

Answer: I personally think yes, I prefer not to use knives with too long of a blade for better control. I use fillet knives as part of my arsenal for large game as well. Of course, like potato chips, you can't have just one...just saying.

Answer: I think the blade is too long. I use mine to fillet Large yellowtail. Over 40” fish. Just my opinion.

Q:

doe's kast king offer a decent sheath w/ belt attachment?

Answer: The knife comes with a hard plastic sheath that has openings down the flat length from hilt to almost the tip. There is a tang at the hilt to keep the knife secured. Unfortunately there is no belt type loop incorporated into it. Haven’t had a chance to filet with it yet but it has an interesting rubber like material covering the handle which gives it a nice grip feel in hand. Not sure if the blade is stainless ( may say in the description) as it has a mat black coating. Hope this helps.

Answer: The sheath is nice. It’s a hard plastic with slotted vents. I don’t recall seeing a belt loop. The knife of now at our home in Mexico so I can’t check that. Quality knife for sure.

Answer: Yes it does

Q:

Which length blade would you recommend for filleting Crappie or Walleye

Answer: 5"

Q:

how is it?Does it work well?

Answer: Works great . Best as a bait knife or gilling knife . I use fir both !

Answer: When I received mine the blade edge wasn't as sharp as they said and the handle looks cool but the material it was made of seemed like it absorb smells from fish over Time so I returned it.

Answer: My brother is a meat cutter by trade and he loves this knife. He says it does a great job.

Answer: It is a nice flexible sharp knife.

Q:

When will the 12” carving knife be available?

Q:

what is the best way to clean it?

Answer: Like most knives and utensils warm soapy water is the best method. I would not recommend the dishwasher. If you’re in the field and use the knife rinse with clean water until you can use dish soap.

Answer: Mine was so dull with no edge when I got it. Tried to sharpen many times. Threw in the trash. Would not recommend- hot soapy water and white vineger

Q:

Does this have a Full Tang?

Answer: No idea but works better than any filet knife we have ever used for large fish.

Answer: Yes

Q:

Where is made?

Answer: Mainland China....

RH : First impressions - Substandard functionality

5 stars for looks, but reduced to 2 because it doesn't cut well (I mean, it IS a knife...).
What I like:
Looks!: The design of this knife is really nice; big comfortable handle and great color scheme.
Features: Straight blade with serrations on top plus gut hook - great combination (I couldn't find elsewhere)
What I don't like:
Sharpness, or should I say dullness? The straight blade at first seems sharp but if you try the paper cutting test, it fails big time. In fact, a fish knife I picked up at Walmart for $2.89 was sharper! After a half hour with my sharpener, it now cuts paper quite well.
The serrated part, while looking cool, doesn't cut very well, just tears what you're trying to cut - bad design.

Elvisfish : Great knife! Would be a good gift.

I was looking at a more expensive knife. At the moment i couldn't stomach paying three times more for the other brand. I got this one. It works well. I like the sheath that allows the blade to dry. It comes in a nice box that is gift-able. I am looking forward to buying another for my cabin and another for my tackle bag.

Amazon Customer : Excellent Fillet Knife

I can say enough about this knife... great ergonomics, ultra sharp, nice scabbard, super flexible and easy to keep clean. No issues at all with this knife, but if I were to buy again, I would go with the 7", as the 9" was a little too long for the fish I am regularly cleaning.

Katie L : Good for fishing Men

The handle is very comfortable, the knife is very sharp, and the back of the knife is versatile. Good for fishing.I will recommend it to friend.

Adam Gardner : Not A Sharp Knife

I immediately returned this knife. It's not sharp. Not sharp enough to shave with. Not sharp enough to cut my finger when run it across the blade. When you test the blade with your thumb like you would any knife, it's got the feel of a dull steak knife at a cheap restaurant. I'm just glad I didn't wait until I was actually preparing a fish I caught. Lesson learned kids. Read the bad reviews too, not just the good ones.

Nicholas H. : Dont buy!

Only reason this product gets any stars is because the handle is cool as hell. Other that it comes dull as sin couldn't couldn't fillet a minnow if your life depended on it

javier torres : READ THE 1 STAR REVIEWS, they're the real ones

DO NOT BUY!! TERRIBLE BLADE!! DULL!! Extremely dull and cheap blade!! Razor sharp? That's a complete lie. If you've ever felt a good blade it is extremely evident before even trying to cut something that this blade is cheap, very dull and will never be sharp no matter how much you try.

When steel is good you can feel it. This is also true when it's junk and you can feel it immediately. Just to be sure I tried to cut paper, see the video. An absolute joke. All the good reviews of this knife have to be paid or faked. Read the 1 star reviews. They are the real ones.

GrimmRoper : High quality and sharp

This is a fantastic knife! I'm planning on buying the 6 inch soon. I like the sheath the knife comes with as it protects it in the drawer. The blade is well made and really holds an edge. My knife came razor sharp right out of the box.

This is an excellent purchase.

pip66 : Sharpness doesn't last long

I use this to cut meat for jerky fish rtc and it was great the first few uses them it seemed the blade was not sharp it was going through the meat easily at first like butter this is only after a few uses. And trying to cut a fish was quite hard barley made it through the fish with a lot of effort. Do you have to continue to sharpen these blades or what.

GrimmRoper : High quality and sharp

This is a fantastic knife! I'm planning on buying the 6 inch soon. I like the sheath the knife comes with as it protects it in the drawer. The blade is well made and really holds an edge. My knife came razor sharp right out of the box.

This is an excellent purchase.

swampseeker : What makes these knives so great?!

These KastKing Knives are amazing. The blade is sleek, very sharp and the handle textures when gripped, feels comfortable and sure. These knives will not come out of your hands no matter what. The German 4116 Steel is also known as a Marine Steel.. They are a steel used in many nautical knives. They also make medical devices from 4116 steel for hygienic applications, due to the high percentage of Chromium added to assure a higher corrocion resistance steel.. Chromium is what makes a steel stainless.. A low quality stainless steel has to have a least 5% Chromium, most stainless steel made will add no less than 10% Chromium to their steel. The 4116 German Steel (also know as the 4116 KRUPP) has 14.50 % of Chromium, which makes it a great knife for saltwater use. Even though there are steel with much higher Chromium added, too much Chromium with weaken the steel to edge retention and flex. The 4116 steel has a fine balance of Carbon, Chromium, Vanadium and Molybdenum which makes this steel so versatile and withstands hard use. It is not an expensive steel to create, but I haven't seen a Chefs knife made out of 4116 steel go less than $100. KastKing has created a masterpiece with these knives.. They are gorgeous and very AFFORDABLE.. If you love knives, (like I do) you will appreciate and enjoy these to your collection..

Mario - Probiotic Gardens : GET it.

This knife is a game changer. Makes my previous knife seem like a spork. Cuts like butter and super badass grip. I love it. I'll be getting my Brother and Pop one for xmas. Thanks Kastking. Products are good so far. You are earning my business.

SharaNYC : Sharp and Strong

Really good fillet knife. The blades are really sharp and strong. The size was good for any fish I fillet so far, didn’t have any trouble. I also purchased the small handheld sharpener which I use few seconds before every job. Keeps the blades sharp like day1. I’ve been using it a few months now with no issues and overall I recommend this fillet knife.

Valerie Zamora : Already planning another purchase

Gave this to my husband as an early anniversary gift! He loved it! He got to try it out today on fish he’d caught. And he was so impressed with how easy it cut. Had no struggle WHATSOEVER with filleting the fish. It was VERY sharp straight out of the box. As he was filleting, he barely touched his thumb, and the knife apparently broke skin. But that just made him happy to know that it’s that good of a blade. I was on the fence about it because of the reviews, but now I’m sold. He wants more! Don’t hesitate to buy! It’s sharp, easy and cuts smooth!

JimE Walker : Beautiful BUTTER knife

When the description states "Razor Sharp", I expect the knife to shave hair on my arm out of the box. Not even close! Maybe it will be razor sharp after I but an edge on it, but that's not what I paid for. I'll be returning this knife and find something better.

Nicholas H. : Dont buy!

Only reason this product gets any stars is because the handle is cool as hell. Other that it comes dull as sin couldn't couldn't fillet a minnow if your life depended on it

Kimberly : Worth it

I bought this as a birthday gift for my fisherman hunting boyfriend who’s always complaining that his knife for fishing isn’t long enough for bigger fish. Being the amazing attentive girlfriend I am, I found the biggest one I could and bought it. He loves it. Since i bought it after fishing season was pretty much over we haven’t used it on any fish but it’s been used on steaks, chicken, ducks and it’s done a wonderful job. It’s sharp as heck, easy to hold, even for my little hands, and will definitely be big enough for catfish next spring.

Mariah Sanders : Must buy!

To be honest I don't know a whole lot about what goes into making a good knife but I can tell you that this is far more then a good knife. It's solid, has good weight to it and and the handle is super comfortable. Most importantly though it is stupid sharp. I have purchased other products from these guys and all of them have passed my expectations. They definitely make high quality stuff and will for sure be purchasing the other sizes to the set.

lucasdonlan : Very sharp & easy for lefties

I was determined to learn how to fillet fish that we catch and wanted to get a "starter" knife. I also wanted something that wouldn't seem awkward to hold since I'm left handed. This one was the least expensive on my list and was almost ready to pull the trigger on a much more expensive knife. The KastKing won out and I'm glad I bought it! Super sharp thin blade that easily cut away the fish skin (and other parts). Easy to hold as a left-handed person. I used it a couple times on our trip and will get a sharpening stone for the next trip. I would buy this knife again!

RH : First impressions - Substandard functionality

Leo Harrison : Must have! Incredible quality at a more than fair price

Must have for any serious outdoorsman. Great price and quality! This knife is not only great looking, but it feels incredible in my hand. Nice cover is a great bonus. The handle has a great wrapping on it that makes it feel like it won't slip when wet. This bad boy is RAZOR sharp out of the box. Excellent flex to the blade. Makes my old fillet knife feel like a piece of junk. I will definitely be buying more of these knives in different sizes. I am totally sold on KastKings products. Super fast shipping too.

Tohner Ville : Dull knife

Read the other 1 star reviews! It's true and the knife is very dull. I can't sharpen this knife and it's frustrating when you're trying to filet a fish.

I'm in the market now to get a new a new filet knife.

Jordan : Stupid sharp and great blade protection

This knife cuts even large scaly fish with ease and also stays sharp through filleting most of the fish in the cooler. Amazing how it keeps it edge and is still a very flexible knife. I will purchase more!

GrimmRoper : High quality and sharp

This is a fantastic knife! I'm planning on buying the 6 inch soon. I like the sheath the knife comes with as it protects it in the drawer. The blade is well made and really holds an edge. My knife came razor sharp right out of the box.

This is an excellent purchase.

anthony orr : Excellent grip even when hands are covered in your catch

Amazing feel to this handle even when your hands are covered in your catch. The blade has plenty of flex to get a nice smooth fillet and stays sharp. I even used it this past winter while ice fishing and it held up to the cold Minnesota winters. Excellent product KastKing!

PrynceAl : Its all in the knife fa real!!

Never buy the walmart brand filet knives and u dont have to buy a Bubba...KK is the truth...I have been fishing for 35yrs and I just started cleaning my own fish like 2 weeks ago, this knife made me look like a pro.

Update 9/19/2021:
On 2nd thought I still give this knife 5 stars but I found myself really questioning this knife when my friend let me use his Bubba...yea I returned the KK and ordered a Bubba. I had to do sharpening already on the KK only after 3 fish, I also didnt like the cutting action I had to do with the KK ....using the Bubba all I had to do was slide the knife thru the fillet....SOLD.

YouTube Product Reviewers : Excellent knife.

While I haven't used it yet it does feel good in the hand. Good quality and arrived semi-sharp. While its not dull upon arrival, you will need to sharpen it more to get easy cuts. Expensive but very giftable as well. I am happy with the purchase. 4 1/2 Stars!

GrimmRoper : High quality and sharp

This is a fantastic knife! I'm planning on buying the 6 inch soon. I like the sheath the knife comes with as it protects it in the drawer. The blade is well made and really holds an edge. My knife came razor sharp right out of the box.

This is an excellent purchase.

Mario - Probiotic Gardens : GET it.

This knife is a game changer. Makes my previous knife seem like a spork. Cuts like butter and super badass grip. I love it. I'll be getting my Brother and Pop one for xmas. Thanks Kastking. Products are good so far. You are earning my business.

Valerie Zamora : Already planning another purchase

Gave this to my husband as an early anniversary gift! He loved it! He got to try it out today on fish he’d caught. And he was so impressed with how easy it cut. Had no struggle WHATSOEVER with filleting the fish. It was VERY sharp straight out of the box. As he was filleting, he barely touched his thumb, and the knife apparently broke skin. But that just made him happy to know that it’s that good of a blade. I was on the fence about it because of the reviews, but now I’m sold. He wants more! Don’t hesitate to buy! It’s sharp, easy and cuts smooth!

Joe : Nice!

Love the soft handle, gives it a good grip and feels great in my hand, cool design and color and comes out very sharp out of the box, great quality, happy with my purchase.

Jordan : Stupid sharp and great blade protection

This knife cuts even large scaly fish with ease and also stays sharp through filleting most of the fish in the cooler. Amazing how it keeps it edge and is still a very flexible knife. I will purchase more!

pip66 : Sharpness doesn't last long

I use this to cut meat for jerky fish rtc and it was great the first few uses them it seemed the blade was not sharp it was going through the meat easily at first like butter this is only after a few uses. And trying to cut a fish was quite hard barley made it through the fish with a lot of effort. Do you have to continue to sharpen these blades or what.

Eddie B. : Handles become discolored and begin to break apart

The knives out of the box were amazing. I own the 9, 7 and 6 inch. Each have great performance and great resharpening performance but, these handles need to go back to the lab. All of my handles became discolored, kinda moldy and breakage of whatever kind of latex ish material they used to cover them
The don't hold up well to a lot of use and lots of washing in my experience. I would love an explanation as to why this is happening with these handles.

Amazon Customer : Worst knife ever!

This is the worst knife that I have ever purchased. Right out of the box it would not slice printer paper without tearing the paper. It would take a lot of work to put a sharp edge on this knife. Do yourself a favor and purchase a name brand name knife and stay away from this junk.

Adam Gardner : Not A Sharp Knife

I immediately returned this knife. It's not sharp. Not sharp enough to shave with. Not sharp enough to cut my finger when run it across the blade. When you test the blade with your thumb like you would any knife, it's got the feel of a dull steak knife at a cheap restaurant. I'm just glad I didn't wait until I was actually preparing a fish I caught. Lesson learned kids. Read the bad reviews too, not just the good ones.

PJM : Works Very Well

I bought this to seamlessly remove the skin from entire fish fillets from the grocery store and it works beautifully. It is razor sharp and the sheath is great for protecting the blade. It also seems like it would go through my electric knife sharpener well when the time comes.

Scott R. : Sharp, flexible, good sheath, easy to use

First things first, this knife has a great sheath that protects the blade from damage (and your stuff from the blade). I love how easy it is to get the knife out, yet how tightly it holds on to the knife when sheathed. Also, it'll never get damaged by water, which is a very nice touch.

Next, the knife is sharp. No two ways about it. I've yet to find out just how long it'll hold an edge or how easy it is to resharpen, that'll come with time.

Finally, it's got a great flex to it. Makes it really easy to slide along a filet.

All together, it's an awesome knife, and you won't be dissapointed.

Capt. Butch Rickey : Great design!

KastKing scores again. This is a beautiful knife with good finger guards and a beautiful case that is ventilated and when returning the knife to the case it locks in place, so you don't have to worry about it falling out when you lean over the side of the boat to land a fish. Wicked sharp. Use fillet gloves! Capt. Butch

RH : First impressions - Substandard functionality

5 stars for looks, but reduced to 2 because it doesn't cut well (I mean, it IS a knife...).
What I like:
Looks!: The design of this knife is really nice; big comfortable handle and great color scheme.
Features: Straight blade with serrations on top plus gut hook - great combination (I couldn't find elsewhere)
What I don't like:
Sharpness, or should I say dullness? The straight blade at first seems sharp but if you try the paper cutting test, it fails big time. In fact, a fish knife I picked up at Walmart for $2.89 was sharper! After a half hour with my sharpener, it now cuts paper quite well.
The serrated part, while looking cool, doesn't cut very well, just tears what you're trying to cut - bad design.

Nicholas H. : Dont buy!

Only reason this product gets any stars is because the handle is cool as hell. Other that it comes dull as sin couldn't couldn't fillet a minnow if your life depended on it

JimE Walker : Beautiful BUTTER knife

When the description states "Razor Sharp", I expect the knife to shave hair on my arm out of the box. Not even close! Maybe it will be razor sharp after I but an edge on it, but that's not what I paid for. I'll be returning this knife and find something better.

Happycamper : Winner-Winner!

So, like most folks during Covid, my Son-in-Law took up fishing. Didn’t have a fish knife, was using a big pocket knife. The fish filets...looked like it. Give him this one: hard to lose, due to bright orange; really great handle, says it really helps him guide the blade; and the fish filets look like an expert cleaned the fish. Winner-Winner, Chicken Dinner!

Just in time : Very comfortable razor sharp fillet knife for the price

First the good-
1 Razor sharp right out of the box
2 Good blade flex
3 Nice packaging and sheath
4 Comfortable in the hand
5 Phenomenal price

The Downsides-
1 While the handle is comfortable and ergonomic it is made of a fabric material that seems like it's not going to do well after getting wet and might absorb and hold some fish slime and smell. Not good silicone like most other brands. But only time will tell.

Overall I'm very impressed but still very concerned about the handle material and wondering why they chose to go that route. I've owned another one of their fillet knives and it had a great silicone or rubber type of handle that was the same price so this is a brain scratcher to me. Probably not good for commercial fishing. Still a nice knife and worth the money.

AMS : Sharp as a sword

Think I read a few reviews about it being dull...this sum bitch is sharp as a Samurai sword. Fits perfect, great size and it looks amazing. I don’t get the bad reviews, very sharp out the box. Great so far

AaronW : Best grips ever

The grips on these knives are amazing. It feels a lot like the Winn grips they put on some fishing rods. Super soft and non-slip. The blade is very sharp, and flexible on this 9" finesse version. I didn't realize how big a 9" fillet knife is before I ordered. It is much larger than the typical fillet knives I have. Great buy!

GrimmRoper : High quality and sharp

This is a fantastic knife! I'm planning on buying the 6 inch soon. I like the sheath the knife comes with as it protects it in the drawer. The blade is well made and really holds an edge. My knife came razor sharp right out of the box.

This is an excellent purchase.
