Blue Steel #2 Magnolia Round Handle with Buffalo horn bolster


The Aideba is slightly thinner and narrower than a Deba Knife. It is suitable for cutting fish into 2 or 3 pieces, skinning and chopping. It is lighter and easier to use than a Deba Knife, but if you use it roughly, such as for boning, the blade tends to spill.

Blue Steel #2

Carbon Steel

Blue Steel #2 contains a small amount of Tungsten, improving hardness and Chromium, improving toughness. This results in a steel that has higher overall edge retention and hardness in comparison to the White Steels.

*NOTE: The Carbon Steel is susceptible to rust if it is not properly cared for. Please clean and dry the blade regularly during use.

Magnolia Round Handle with Buffalo horn bolster

Forge Welded

Forging Process

A forge welded blade is essentially a blade made of more than one billet of steel. There are many variations of technique and steel combinations. At its most simple, a forge welded blade is two billets of steel heated and hammer together to form one unified piece. The steel will then be shaped by hammer into the desired blade shape. Hardened and tempered, then ground, sharpened and polished. A forge welded blade has higher strength and edge retention than a stamped blade.

A knife store that has supported the history of knives and food culture in Japan.

It has been 600 years since the birth of swordmaking in the Sakai region of Japan. Sakai Ichimonji Mitsuhide's and it's craftsmen continue to build on that legacy by producing the finest blades in Japan.
This is where the culture of completing a dish of sashimi by "just cutting" and the culture of expressing sharpness as "taste" was born.
For 70 years, we have been connecting the spirit of Sakai's craftsmen with the passion of chefs in Osaka's kitchen equipment shopping district, known as the kitchen of Japan.
We are very happy that our knives can be used by people all over the world.
