Yasuki Sirogami carbon steel which is hard and have sharpness, have been used by professionals for a long time in Japan. This steel is pure high carbon steel that impurities removed.

Note:

Carbon Steel is sharp. So many people prefer the sharpness of carbon steel. But carbon steel is not rust resistance. Rust will appear. Please wash, wipe and dry it up well after use. In case rust appears on the edge, remove it by a sharpening stone. In case rust appears on the blade, use cleanser(in case of stainless steel) or scourer(in case of iron steel). (scratch may appear)
Don't twist edge, and don't cut and hit frozen foods or bones, the edge will be chipped or broken since the blade of Japanese is thinner for sharpness.
