Features

  • Razor Sharp Stainless Blades All new KastKing fishing fillet knives and the 5 Bait Knife utilize premium, razor sharp G4116 German Stainless-Steel blades with a beautiful black finish. KastKing fillet knives will maintain their edge longer in both fresh and saltwater applications and make the job of cutting baits, filleting fish of all sizes and steaking large game fish easier than ever before.
  • Non-Slip Super Polymer Grip - We use the most comfortable and slip-resistant, super polymer grips for your safety and comfort. These handles feel great in your hand and ensure that you always have a solid grip on your fillet knife. These handles also clean up easily and stay looking good longer.
  • The Right Knife For The Job - The 5 Bait Knife is stiff and strong, it has a serrated top edge that makes cutting frozen bait quick and easy. The razor-sharp leading edge allows the fisherman to easily prepare both chunk and cut plug style baits. The 6, 7 & 9 Fillet Knives are not only sharp and but also have the perfect flexibility so the knife will follow natural contours for perfect fillets. The 9 Steaking Knife is a powerhouse for steaking big game fish like salmon, tuna and more.
  • Includes Protective Knife Sheath Each knife includes a light-weight and durable sheath to protect the blade and keep you safe in between jobs. The unique design of the sheath will lock the handle in for safety but removes easily when needed. The open slots in the sheath are design to allow water to drain easily so that your knives stay dry and sharp.
  • Affordable Innovation KastKing fishing knives are available in the most requested lengths and shapes so that youll always have the right tool for the job. Available from a beautiful 5 bait knife all the way to a tough 9 steaking knife for the biggest game fish. All KastKing fishing tools are covered by our total peace of mind warranty against the workmanship and materials for the original owner. We have total confidence in the quality of all KastKing fishing tools and so will you.

Oh my goodness! This is a fabulous knife. I have had this in my save for later list for a very long time but didn’t want to spend the money. Finally I decided to just buy and it was the absolute best thing. Love this knife!! I don’t use it to fillet fish but to clean up the meat we buy. It cuts like butter. ... show more

  • Cant wait to catch some fish!
Color: C: 7'' fillet Knife
I first ordered a lower priced knife from the same company and did not like it. I tried this one and was so much better for a few dollars more. Fit my hand and felt like it would not slip out when wet. Blade was better quality also. Customer service from seller was helpful with the new purchase

  • Fantastic
Color: D: 9'' fillet knife
This is the best filet knife ever. Be careful extremely sharp. Use to filet fish and carve meat. Blade length long. To avoid injury, use some cutting gloves.
