Its an american angler electric knife, i bought a set of thin berkly blades for small fish. The tool is a townsend fish skinner. I dont think they make them anymore, they were made in america, probably circa 1950-60. You can still find them for sale though online. Saves a lot of meat on small fish fillets and pulls some of the belly bones out. I still go back throu with a fillet knife and make sure the bones are gone. As for cheating, my old USMC drill instructor used to say, " if your not cheating, your not trying hard enough".....LOL!
