The SLD Difference
SLD is a semi-stainless tool steel - harder and more wear-resistant than typical stainless steels, with edge retention closer to carbon steel, but with enough chromium content to resist rust far better than pure carbon. The washiji fine pear-skin finish reduces drag and prevents food from sticking to the flat. The yaki oak handle is charred/scorched for a distinctive dark, textured appearance that is unique to this line. Made in Japan by Tsunehisa.
Care & Maintenance
Hand wash and dry - more rust resistant than carbon but not fully stainless
Sharpen on Japanese water stones
Hone regularly with a ceramic or fine honing rod
Keep the oak handle dry - do not soak
Store on a magnetic strip or in a knife block to protect the edge
