Masashi-Kobo
Masashi Yamamoto is the nephew of Tsuneo Yoshida, the owner and former master knife-maker at Yoshikane Knives and he learned his art at the hands of Yoshida san. As Yoshida san slows down and has effectively retired from the Yoshikane company, other nephew Kazuomi Yamamoto has taken over the company.

Masashi Yamamoto has left Yoshikane to set up his own business and that company is
Masashi-Kobo.

The initial Masashi offering is a beautiful range of knives, revolving around
SLD steel, polished to a stunning finish.
