The steel

We all know that steel is the main material of a knife. All over the world knife makers are making a knife with different kinds of steel. Every Japanese knife maker is very sensitive to the steel. Yoshihiro is the boss of them. In order to make this Japanese Sushi Knife, they use aoko blue steel#1.

There are two kinds of blue steel. Yoshihiro used grade #1 in this knife. It is very hard. In the Rockwell scale hardness is 64-65. Only the master artisans of Yoshihiro can forge the blue steel#1 with iron with a very sincere process. Their perfect blending process makes the steel a superior item.

When you look at the blade you can see a marble like a pattern on the surface of the knife. It is called suminagashi. It’s a Japanese word. It means floating ink. This excellent marbled look pattern gives the knife an outstanding appearance that you don’t find in any other knife.

When you sharpened the blade it unveils the new design of patterns. The master artisans of Yoshihiro makes this magical blend of metals with their priceless experience. This is a Yanagi knife. Yanagi knife is long blade knife. It is very easier to cut sushi sashimi with a long blade of Yanagi knife. It provides an uninterrupted cutting stroke through the food.

The Handle

Being a Yanagi type knife this knife needs a heavy and long handle. Japanese knife makers always use a good quality wooden handle. In this Japanese Sushi Knife, Yoshihiro uses an octagonal shaped wooden hand. It is made of ebony. Ebony is a dark wood veneer. The shiny wooden handle gives the knife a stunning look. The octagonal shape helps not to slip the handle from your hand.

Additionally, the handle doesn’t hurt you at all. This type of handle is comparatively comfortable than any other handle you have ever seen. Moisture absorbing is an important issue here. This wooden handle does not catch moisture.

A bolster is affixed to the handle at the top part of it. It is made of water buffalo horn. A bolster is situated at the junction of the knife blade and the handle. For a good transition from the blade to handle a quality bolster is used. It enhances the durability of the handle as well as the knife.


Japanese knife makers use carbon steels which are not stainless. They used carbon steel because it is harder than stainless steel. Japanese knives have a sharper cutting edge. In order to keep a sharp edge the steel has to be hard. Although the steel is not stainless, so you can use it for a very long time with care. It needs little more care things.

Always try to keep it dry between uses. Wipe it with dry cloths. Use Tsubaki oil which is included with the knife. Store the knife in a dry place. I personally suggest using a knife block. There are beautiful knife blocks in the market.
