The wash away fillet tool is a new cutting board utensil designed primarily to be used to fillet fish; although, it could be used for other similar jobs. The design is a straightforward improvement of the cutting board which makes the job of filleting fish safer, cleaner, and faster. A water chamber attached to a cutting board is the key part. The water chamber permits water to flow across the working surface of the fillet tool. The flow of water washes undesirable waste material off of the fillet tool keeping the hands and knife free of fish slime.
