KastKing Fillet Knife Product Review

KastKing utilizes razor-sharp G4116 German stainless-steel blades with a sleek matte black finish. These knives remain sharp and perform excellently in both fresh and saltwater environments.

The KastKing Fillet Knife easily slices through baits, steaks large game fish, fillets fish of all sizes and trims fish from the bone effortlessly. Plus, the stainless steel blade is flexible and has a nice small tip for intricate work around and in between the bones.

The non-slip super polymer grip provides comfort and slip-resistance for a handle that feels secure in the hand. Hate mess? These handles clean up quickly and look good-as-new after every use.

These knives are available in sizes 6″, 7″ and 9″ including a protective knife sheath to protect the blade and keep you safe inbetween jobs. The sheath’s unique design locks the handle for safety, and the open slots allow water to drain easily, so your knives remain sharp and dry.

The budget-friendly price tag makes this a knife that’s hard to beat. The construction and characteristics of the blade hold an edge well and are easy to sharpen with a few glides over a straight edge.
