A fillet knife is a specialized kitchen tool designed for filleting fish and other delicate meats. It features a long, thin, and flexible blade that allows for precise cuts along the bones and skin. The flexibility of the blade helps to separate the flesh from the bones without tearing, making it ideal for tasks that require finesse. Fillet knives typically have a comfortable handle for a secure grip, which is essential for safety and control during use. They come in various sizes, catering to different types of fish and meat. Proper care, including regular sharpening and cleaning, ensures the longevity and effectiveness of a fillet knife.
