Takami 52mm Watetsu / White I Steel blade Kamisori double bevel edge---3
It is double bevel edge blade, and it has concave on the both sides (watetsu on the one side with hagane on the edge and hagane all on the other side). The Jigane (soft iron, the body of the blade and the handle) is made out of Watetsu that is very soft iron from 200 years old hardware, so it is much easier to sharpen than Goku Nantetsu (contemporary mass product soft iron). Hagane (steel, the edges of the blade) is made out of Hitachi white I steel which is pure high carbon steel(white I B: C;1.2-1.3, white II B: C; 1.0-1.1).
Watetsu is the iron that is byproduct with Tamahagane, when Tamahagane (approximately 0.8% to 1.5% carbon content) is made in Tamahagane steel manufacture (Tatara iron making). Watetsu is approximately 0.1% of carbon content, so it cannot use it as the steel (Hagane) . Watetsu is used as excellent Jigane (softer iron), because it is very soft, and easy to sharpen and easier to raise the slurry, and feel excellent during sharpening, and great shock absorber. Japanese carpentry blacksmiths who make high quality chisel or plane use Watetsu for those high-end cutleries of Jigane. Watetsu shows very nice layers of iron, because it has to be hold over so many times to homoginize watetsu product. There are some things to hard to obtain Watetsu : One is what we have to make own Tamahagane, because Watetsu is a part of Tamahagane (byproduct). Or the other way is to find over 150 years old or older high quality iron products like high quality old hardware made by Tatara steel manufacture (Samurai era in Japan was closed country, so there is only Tamahagane had existed, I meant we have to find old Watetsu from recycle like this razor).
Watetsu is made out of charcoal and iron sand, and it is not homogenized, so It has to turn over so many times the Watetsu to be homogenized as high quality iron product, and plus to remove unwanted part of steel or some other ingredients in Watetsu by turning over and pounding and heat up.
It costs much more (everything is not useable, and it takes much more times to make watetsu than just using just ordinary Nantetsu from contemporary steel that is made by steel or iron manufacture company.
However, the Jigane by Watetsu looks beautiful natural Damascus, because it is turned over so many times. It also shows black lines between layers sometimes, because it is made from not homogenized steel.
Even one of greatest carpentry blacksmith, Mr. Chiyozuru, Korehide made Japanese plane Jigane shows some black spots, but it looks more beautiful than without it (beauty of imperfection). As long as it makes no trouble for using it, it should be O.K. The Hagane is Hitachi white I steel that is pure high carbon steel like white II steel, but it has more Carbon content in the steel that is able to higher HRC than white II steel. White I steel is pure carbon steel, so it is not easy to success the quenching and tempering processes.
