The KastKing SteelStream 6pc Fishing Tool Kit is a versatile set designed for fishing enthusiasts who want a complete package of essential tools, including a fillet knife. The fillet knife features a 7-inch blade made of 420 stainless steel, known for being tough, rust-resistant, and easy to sharpen. This makes it a good choice for filleting fish efficiently. The blade is fixed and appears to have moderate flexibility, suitable for precise cuts without being too soft.
