The Yanagiba is primarily used to slice boneless fish fillets for Sashimi and Sushi dishes, but it can also be used to fillet small to medium-sized fish, and is often used for skinning fish. The narrow blade and relatively acute edge angle of the Yanagiba are features which greatly reduce the effort required to cut through ingredients. As with the Sujihiki, the long blade allows the fish to be cut in one single drawing motion, from heel to tip. 

The combination of cutting technique, acute blade angle, and sharp edge result in very little cellular damage in the cut surface. This is particularly important for dishes where the fish is eaten raw, because it helps to preserve the original flavor and texture of the fish.
