The core of the blade is made from hard SLD steel and is clad in softer stainless steel. SLD contains 1.5% carbon for an HRC of 60-62, as well as 11-13% chromium for stain resistance. Through a special heat-treating process, Masashi-san is able to get SLD incredibly hard, giving it edge retention on par with high-end carbon steel. Despite the stainless steel nature, you’ll still want to dry it off after each use.
The handle is made of Japanese Pagoda wood with a water buffalo horn collar and is an oval shape giving optimal comfort to the right and left-handed alike.
The kanji on the knife blade “聖作” means “Masashi Saku” or “made by Masashi”.
