The invention is a Y-bone fish fillet knife, a specialized Y-bone fish fillet knife blade and methods of using same to debone fish having Y-bones. Features of the novel Y-bone fish fillet knife and its specialized knife edge include an intentionally unsharpened, or rounded edge, notched groove and an arcuate cutting edge. The rounded notched groove tracks and slides along the Y-bones during cutting. The cutting edge may have other shapes and be dual-edged according to other embodiments. The knife and its handle are designed for ambidextrous use.

The fish descaling tool is adapted for use with a fish. Specifically, the fish descaling tool is a hand held device that is designed to remove scales from fish. The fish descaling tool is an electrically powered device that rotates a scaling cylinder in such a manner that the scaling cylinder will remove the scales of the fish without damaging the underlying flesh of the fish. The fish descaling tool comprises a scaling cylinder, a hood, a handle, a motor, and a power source.

A Retractable Venting Tool has a needle with a point and an opposite shank, a knob connecting to the needle proximate the shank, a barrel receiving the needle and a primary slot guiding passage of the knob, a front spring near the tip, a rear spring away from the primary slot, and a clip outside of the barrel. The barrel has ridges outward of the primary slot, a shoulder outward of the ridges, and a head opposite the tip. The front spring compresses upon advancing the knob and needle outwardly from the tip. Upon completion of venting of a fish and turning the knob, the front spring retracts the needle abruptly. The rear spring compresses upon the knob being furthest from the tip. Before venting a fish, the rear spring imparts an axial force to the needle and cooperating with the knob retains the needle inside the barrel until needed.
