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, making it easier to separate the flesh from the skeleton. The sharp edge ensures clean cuts, which is essential for maintaining the quality of the meat. These knives often have a comfortable handle for a secure grip, enhancing control during use. While primarily used for fish, a fillet knife can also be effective for other tasks, such as trimming fat from meat or slicing through soft fruits and vegetables.
