The Jigane is made out of Watetsu that is very soft iron and very low percentage of Carbon, so it is much easier to sharpen than Goku Nantetsu (soft iron). It is the one of the best Jigane in Japan, but it is hard to get it.
Watetsu is the iron that is produced with Tamahagane, when Tamahagane (approximately 0.8% to 1.5% carbon content) is made during Tamahagane steel manufacture, however Watetsu is approximately 0.1% of carbon content, so it cannot use it for blade edge (Hagane) . However, Watetsu is used as excellent Jigane (softer iron), because it is very soft, and easy to sharpen, and feel excellent in sharpening , and great shock absorber. Japanese carpentry blacksmiths who make high quality chisel or plane use Watetsu for those cutleries of Jigane. Of course, Japanese sword blacksmiths use Watetsu for Jigane of Japanese sword. Watetsu shows very nice layers of iron, because it has to be hold over many times for homogenized to be watetsu products. There are some hard side of Watetsu : One is what we have to make own Tamahagane, or the other way is to find 100 plus years old steel products like high quality old hardware made by Tatara steel manufacture (a part of Tamahagane, I meant we have to find old Watetsu to recycle).
Watetsu is made out of charcoal and iron sand, and it is not homogenized, so It has to turn over many times to be homogenized iron product, and blacksmith has to remove unwanted part of iron or steel in Watetsu.
It costs much more, and it takes more hours than just using ordinary Nantetsu from steel company.
However , the Jigane by Watetsu looks natural Damascus, because it is turned over so many times uneven soft iron layers. The Hagane is Kikuksui white II steel which is high carbon steel (pure carbon steel). Yahata Steel Co. Kikusui that is pure high carbon steel like white II steel. It is over 60 years old hagane that we cannot purchase it anymore.
