Deba Knife is the Japanese version of filleting knife. It can be same size as Santoku Knife, but it's more curved. They are perfect for fillet fish or removing meat from bone. The heft of the knife allows it to cut through the head and bones of a fish, and the smaller pointed tip fillet the flesh from the bones. The Deba Knife can be used for chicken and meat as well but not recommended for cutting through large bones.
