Isamitsu

Experience the Beauty of Traditional Japanese Craftsmanship

Isamitsu is a relatively new knifemaker, based out of the Ibaraki Prefecture near the Tokyo region. Run by two master bladesmiths ‚ÄĒ Yhuki (blacksmith) and Gaku (sharpener) it is one of the smaller Japanese knife forging companies. Both bladesmiths apprenticed under the famed Teruyasu Fujiwara, who is considered to be one of the best knife and sword makers in Japan.

Isamitsu creates entirely handmade, authentic Japanese chef knives. Each knife is unique ‚ÄĒ perfected over hours and days of labor using centuries-old skills passed down across generations of Japanese blacksmiths and artisans.

They use only the highest-quality crafting materials for their knives, including high-carbon steel, such as Aogami Super (Blue Super Steel), Shirogami (White Steel #1), and Aoniko (Blue Steel #2). They fashion the handles out of locally sourced wood, such as maple and burberry.

Kitchen knives have a special place in Japanese culinary tradition. Chefs revere them for their unmatched precision and quality. Experience this tradition first-hand with your very own Isamitsu kitchen knife.

Taking Care of Your Isamitsu Knife

Authentic Japanese knives, require regular maintenance to guarantee peak performance. In fact, with the right care, your knife can last you a lifetime and become a valued family heirloom.

It is recommended to minimize contact with moisture for your knife to prevent rust and corrosion. Wipe it down immediately after use and store it in a dry environment. Hand-wash it instead of using a dishwasher. Periodic applications of Tsubaki Camellia Oil will also help with preventing rust.

If you have a single-bevel knife, a whetstone is necessary to help preserve its razor-sharp edge. You will notice the difference between a well-honed Japanese blade in the perfectly translucent slices of produce or impeccable cuts of sashimi it consistently delivers.
