Tamahagane, which in Japanese literally means "jewel steel" or "precious steel", is a type of steel made in the Japanese traditional way. Tamahagane is made by smelting iron sand in a clay furnace called "tatara" and mixing it with charcoal to produce steel with various carbon content. This very laborious process takes as much as 3 days. After the smelting process, the tatara is broken and the steel bloom or "kera" is broken and swordsmiths segregate and collect the steels with various carbon contents.

Making a katana from tamahagane requires high level of expertise from the swordsmith. Swordsmiths will laminate the different types of steel collected from the kera to create a sword which has a hard edge, soft core and springy sides.
