Questions about KastKing Spartacus Fillet, Boning and Food Prep Knife, Razor Sharp 8Cr14 Stainless Steel Blade, 7 Inch

Just released july 2019. But how does the blade hold up to perch or walleye tough skin?

Answer: have used mine about a dozen time ad so far it is still as sharp as the day I got it

How do you get fish bits out of the solid sheath? The air hole looks rather small from the pictures.

Answer: Never an issue, lay the sheath aside and clean the fish. Wash all off and back together.

So, the steel in this blade is 8cr14, not 8cr14MoV?

Answer: It's actually a hybrid 8cr14 and a MoV which allows you to use the HOV carpool lane!

7" Spartacus filet knife question. The key to filetting fish is a sharp flexible knife and good feel. Is it light enough to feel the bone edges?

Answer: Yes,you can definitely feel the bones. This knife is EXTREMELY sharp and easy to resharpen. I use the 7" knife on larger fish like walleye and bass and the 5 " knife for panfish.

Answer: Yes, a excellent filet knife needs a flexible shape blade to feel the bone edge and a handle that feels good in the hand.

Product reviews of KastKing Spartacus Fillet, Boning and Food Prep Knife, Razor Sharp 8Cr14 Stainless Steel Blade, 7 Inch

Jane Doe Reviews : Good value, solid knife.

Purchased this based on some other good reviews and the price point. The grip is fairly large for my small hands, but it feels solid and sticky/textured enough not to slip with wet/slimy hands while working. The 7" has plenty of flexibility without being to limp. The blade fits well into the provided hard sheath and engages securely with an audible click when completely secured. The sharpness seems pretty good straight from the box. I'm looking forward to seeing how the edge retention holds up with continued use. So far, so good. I'd love to see this model in a smaller size like a 4-5" for more delicate work.

Amazon Customer : Good knife

I was quite happy with the knife in almost every regard except for the blade shape. My particular unit arrived without a tip. It either broke off or was not ground fully up to the tip. It was not a big deal for me as I used a knife sharpener to make it nice an pointy again. I do highly recommend this knife in ever other regard.

kwalker : Very happy with purchase

Steelhead : Sharp, Great Finish, Excellent Quality

I love everything about this knife but one thing. I think the handle is a little large for the shorter blade length. That said, the knife is very sharp, nicely coated for rust resistence, very non-slip grip, and nice fitting sheath. Overall, I am very pleased with this knife and will buy this model again.

Jay Dee : Good bang for your buck

Great quality knife so far. Sharp right out of the box. Time will tell how it will hold up over time but a very good bang for your buck.

Amazon Customer : Good knife bad cover

Everything was good. Filleted really well, looks nice.
One big point that I give this nice was that cover is too loose to hold the knife.
I purchased this one because of cover(the one that I considered didn’t have a cover)
But nothing different has cover or not.

That was big frustrating .

Jaime Anderson : Love this knife!!!

This is one of many Kastking products that my 5 yr old son received for his birthday. As scary as it sounds to have a 5 yr wielding a knife, he uses it like he's been cutting bait for years! The knife is very flexible and fits comfortably in your hand. We absolutely love, love, love our Kastking gear!!

Ryan Burton : Great for any user

I've always used hand me downs knives and have struggled to clean fish with any consistancy. This knife is sharp out of the box and ready to use. Made cleaning my last batch a panfish a breeze.

Kevin S : Great Product

Great product and great quality for the price

Robert Z Raynor : Great Fillet Knife

Great feeling knife and well made!

Derek Pulvermacher : Nice for the price

Sharp knife, has a nice flexible blade for filleting panfish.

Jaime Anderson : Love this knife!!!

Jim334 : Dull Dull Dull

This is the dullest knife I've ever bought in my life.... It came extremely dull and IMO isn't even worth the $25 price. If you buy it you'll have to take it directly to someone who can put an edge on it for you because it's definitely not ready to fillet anything out of the box. It would probably cut cake fine but that's about it. Look elsewhere.

Butt3rBean : You will not regret buying this knife.

What a great buy! Perfect handle, grip & size.
Not to mention the snap-in sheath

Steven Mansfield : One of the best I've used

Stays sharp

Randy Randerson : Solid Knife, Great Value

Well built, handle feels great. 7" fits perfectly in the front pocket of my tackle bag. No complaints here.

Nik L : Very good value at the price point ...

After shopping several other options at different price points, we settled on the 7" Spartacus to replace an older, worn-out fillet knife. We are happy with it so far, the knife handles well and feels durable, and the blade has a good combination of flex and backbone. Very similar to a recent review from May 12, we were a bit concerned that the one we received didn't appear sharpened all the way to the tip -- it's slightly rounded at the end, and had pushed through the packaging when we unboxed it. But after sharing the attached photos with Kast King customer service, they said the knife is within specs and that their warranty would cover a replacement should issues arise.
