SLD Performance in the All-Rounder
The Santoku's flat blade profile and blade height make it ideal for the push-cut style - clean, full-contact cuts through vegetables, proteins, and herbs without the rocking motion. SLD semi-stainless delivers carbon-like sharpness and edge retention with significantly better rust resistance than pure carbon. The washiji fine pear-skin finish reduces drag. The yaki oak handle is charred/scorched for a distinctive dark, textured appearance. 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
