Blue Steel #1

Blue Steel #1 has a higher concentration of Tungsten and Chromium than Blue Steel #2 , resulting in a sharper blade.Many Blue steel knives at Sakai Ichimonji will feature a traditional "Hamon" or Wave like pattern defining the harder steel from the softer steel.NOTE* This is a Carbon Steel , which means it is susceptible to rust if not properly cared for. Please clean and dry the blade regularly in between use.

Yew octagonal handle
Handle
These handles are made from Yew wood, this wood was historically used in European Longbows due to its density, strength and rot resistance. It was also used by Prince Shotoku , a regent in the Japanese Court.This wood is characterized by its beautiful grain and a color that darkens with age.

Forge Welding
Forging Process
Forging is the main process for producing high quality blades.A craftsmen will heat a piece of Steel in a forge, and repeatedly strike it with a hammer, shaping the Steel into the desired blade shape and also at the same time refining the grain size and driving impurities out of the Steel. The blade is then hardened and later tempered to relieve stress.Forging generally produces a superior blade to the more common stamping method used by large companies.

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.
