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.

  • Great for hunters, not just fish.
Color: E: 9'' strong fillet knife
I am a hunter and use the 9" Strong Fillet Knife to break down elk and debone the meat. It is perfect for this task. I have butchered several elk with it. The rubberized grip helps maintain control. The blade stays sharp and the occasional (2-3 times over the course of a big animal) steeling keeps it going strong. Blade shape is great for following the bone and getting every ounce of meat. The tip is sharp and useful for fine work. The plastic sheath allows the blade to dry and the knife positively snaps into the retention. I would definitely buy again. Top notch product. ... show more

  • Sharp! Quality Seems Good. Great for butchering and trimming meats of all sizes!
Color: E: 9'' strong fillet knife
Bought this to butcher and trim meat for smoking. VERY sharp. I like the handle and curve of the knife which are both good for butchering and trimming meats of all sizes. The orange and black is kind of cool, but does not affect the performance! The quality and weight also feel great. I am very happy and will update if I get any issues with quality or holding an edge, but so far very, very good! ... show more

  • Good value knife

The long blade has just the right amount of flex to make filleting fish easier. I like the sheath it comes with too.

  • Great knife. Very surprised!
Color: E: 9'' strong fillet knife
Great knife. I was shocked at how well it performs. It does better than all of my Dalstrong knives. Just purchased a set since this one was so impressive.

  • Shop no further!
Color: E: 9'' strong fillet knife
Arrives super sharp, stays super sharp! I have used multiple popular brands that are more expensive but do not last as long. This is definitely great value! The grip is super tacky and although the knife feels a little delicate, it has reamained durable through extensive use. I will definitely be buying more in different sizes. ... show more

Color: E: 9'' strong fillet knife
Fantastic carbon steel knife. It is stiff, easy to keep sharp and has a well designed holder. It is very similar to bubba knives at a much lower price point.
