Yoshihiro Blue High Carbon Steel #1 Masashi Kurouchi Series

The Masashi Kurouchi series pairs a core of Blue Steel #1, one of the hardest traditional Japanese carbon steels, with a rustic kurouchi (black-forged) finish. The dark forge scale left on the upper blade gives each knife a handmade character and helps protect it from moisture.

The series includes petty, petty-kiritsuke and other shapes with shitan wood handles, in sizes such as 135mm and 150mm. Blue Steel #1 holds a keen edge for a long time and is a pleasure to sharpen on a whetstone. Dry the blade after use and protect it with camellia oil.
