Montanren refers to the wavy pattern on the back side of the blade, where the boundary between soft iron and steel is wavy like the blade pattern of a Japanese sword. This requires a high level of skill, and there are only a limited number of craftsmen in Sakai who are able to do this.

Yanagiba (Sashimi Knife)
Yanagiba knives are mainly used for cutting Sashimi. The sharpness and edge geometry is of the utmost important with a Yanagiba, as a dull knife will damage the delicate fibres of the fish. The blade is long, slender, thin and sharp for cutting sashimi in one stroke. In addition to cutting sashimi, this knife is also used for pulling the skin. Professionals use long Yanagiba knives with blades around 300mm. For home use, Yanagiba knives with a blade of around 210mm are popular.
White Steel #1
White Steel #1 is the closest to traditional Japanese Tamahagane steel. It is extremely pure, with a very high carbon content allowing for maximum edge retention.
White Steel#1 is a higher Carbon content version of White Steel#2, making the steel harder and better at cutting, but also more difficult to sharpen.
This is the steel type most often recommended at Sakai Ichimonji for those seeking the ultimate edge and sharpness.
*NOTE: Carbon Steel is susceptible to rust if it is not properly cared for. Please clean and dry the blade regularly during use and after use.

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.
