This Yoshiro Mioroshi-Deba has a beautiful mirror polished finish, elegant Japanese Rosewood octagon handle with a Water Buffalo horn bolster affixed and a White Oak Saya cover. Like a Deba, it exhibits the characteristics to butcher a whole fish. It has a narrowed blade and thinner spine which allow for finer detailed work. Gin-san, also known as Ginsanko is a high performing stainless steel. Yoshihiro master blade-smiths use traditional forging methods mixed with modern techniques and strengthening elements of Carbon, Chromium, Manganese, Phosphorus, Sulfur and Silicon. The result is a knife that sharpens with ease and holds its edge. Extremely user friendly, Gin-San is a popular blade choice for single-bevel knives among all ranks of chefs.
