About This Item
Takami Kamisori 52mm Rentetsu / White I Steel blade Single bevel edge Straight Razor With synthetic leather case (made by Shigemori Aoki)
It is single bevel edge blade, and it has concave on the both sides (Rentetsu on the both side). *Hagane---steel (white I steel) *Rentetsu----wrought iron (very low content of Carbon in iron, less than 0.08% of Carbon content which is softer iron than normal mass product iron and easier to raise the slurry) *Jigane---iron The Jigane (soft iron, the body of the blade and the handle) is made out of wrought iron that is very soft iron from 19 century ( I guess, after that, no one producted), so it is much easier to sharpen (smoother) or easier to raise the slurry 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).
Wrought iron is used as excellent Jigane (softer iron), because it is very soft, and easier 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 wrought iron for those high-end cutleries of Jigane. Wrought iron shows very nice layers of iron, because it has to be hold over so many times to be homogenized product. There are some things hard to obtain wrought iron: One is what I guess no one make it right now. The other way is to find over 100 years old or older high quality iron products like high quality old hardware old rail road or old ship or old train, or old bridge or for example, Eiffel Tower is used wrought iron a lot. I meant we have to get old wrought iron products by recycling like this razor.
To recycle wrought iron has to turn over many times, so it comes out Damascus pattern naturally. It costs much more (everything is not useable, even though it takes more time to be the product).
However, the Jigane by wrought iron looks beautiful natural Damascus, because it is turned over so many times. 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 (highest pure carbon steel in Hitachi Steel Co.).
