Tamahagane steel is made from iron sands and is used to make mostly swords. This material is made traditionally by constructing a large clay furnace called a tatara and heating it up to about 1800 degrees Fahrenheit. The iron sands mix with the charcoal used to fire the furnace and this imparts carbon to the steel and makes it suitable for knives and swords. It's a technical process and they still make steel using this method in part to keep the tradition alive. We will be offering some special kitchen knives made with Tamahagane steel soon in very limited quantities.
