This knife is called Yanagiba knife which is used for slicing sashimi, peeling vegetables, and cutting most of soft ingredients very accurately. The blade is made out of Yasuki Shiro II ko (white II steel) which is very suitable for high-end Japanese chef knives. Shiro II Ko Steel is pure high carbon steel, so it is stain or rust, but if you want very sharp edge, white II steel is the one, because the steel molecule structure is smaller than alloy steel. To preventing the stain or rust, Japanese chefs scrub little bit water and comet or Ajax cleanser or any kitchen cleanser with soft sponge or towel or soft wood block or rubber block. White II steel forging temperature is very limited like 730 degree Celsius to 760 degree Celsius, so to make white II steel blade knife is not easy as the other steels added other substances like a stainless steel, and it is important to have great skill and experiences by blacksmith.
