OUL 150mm Wa-Petty. Blade is forged with Ginsanko stainless (silver 3 steel). Cherry wood octagonal Kijiro Urushi lacquer.
The OUL Ginsanko series knives are forged by Naotaka Yamatsuka, one of the few Sakai blacksmiths that forges with Ginsanko. They are very easy to sharpen and don’t rust! They are ground by Maruyama-san, a very talented up and coming sharpener, and have excellent, thin grinds.
Ginsanko is a fine grained, high carbon content (1% + carbon), low chromium (13%) stainless steel with the cutting and sharpening feel of a carbon steel, but less maintenance with regard to reactivity.
