Deba knives are Japanese carving knives. You immediately recognize a deba knife by its remarkable blade. The spine of the blade is rounded and ends up in a sharp tip. Designed to fillet fish (bones and vertebrae) and shellfish. To be able to withstand breakage, the blade is somewhat thicker than the blade of a carving knife and the edge is often sharpened on one side while the other is hollow. The deba knives with a one-sided grind can only be used by right-handed users. Are you a left-handed user? If so use a deba knife with a double-sided grind.
