Deba & Funayuki (Fish Knife)
The Deba and Funayuki are traditional Japanese kitchen knives which are used by chefs for fish, or as utility knives on fishing boats.
Most Deba and Funayuki knives have a single bevel grind, with a thicker, heavier and shorter overall build. Although they are generally a specialist fish knife, some modern chefs do use these knives for other tasks such as breaking down meat and poultry. Deba knives excel at fish filleting, they are not intended to cut through bone.
