Small Blade. SLD Precision.
The petty knife is the Japanese equivalent of the Western paring knife - used in hand for peeling, coring, trimming, and all the fine detail work that a larger blade can't reach. SLD semi-stainless delivers carbon-like sharpness and edge retention with significantly better rust resistance than pure carbon. 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
Keep the oak handle dry - do not soak
Store on a magnetic strip or in a knife block to protect the edge
