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.

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.

Great form factor, and I like the sheath it comes with. However, now I need to buy a sharpener because it was literally impossible to fillet a fish with.

Extremely sharp comfortable handle

b myers : nice knife

I use this knife in the kitchen. It sharpens easily, and the handle does not slip from my hand when I am cutting up messy stuff. My only complaint is that the handle is hard to clean, but I would rather have that then use a shiny, easier to clean smaller handle knife.

Exactly what I expected! Perfect flex in the blade. Razor sharp. The plastic case that comes with it snaps down perfect. Overall fantastic!

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.

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!!

Amazon Customer : Great quality

No need to blow a bunch of money on a fancy knife, this one will do the job. Has been able to handle any fish I've thrown at it yet. Red Fish, Sheepshead, Snapper, Catfish, Black Dum. You name it.

Spend your money on more fishing lures.

Steelhead : Sharp, Great Finish, Excellent Quality

Sean : GREAT PRODUCT

Best filet knife I have ever owned.

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.
