The carbon content of T10 steel is very high, about 1.0%, and its silicon content is up to 0.35%. It is often referred to as "high speed steel". It is more scratch-resistant, abrasion-resistant and moderately resilient than most other types of steel. After the tempering process of our sword masters, the hardness is higher and the wear resistance is better. It is one of the high-quality forging materials. This kind of steel generally only appears on high-end swords. Coolkatana offers high-end katana forged from T10 steel. All are designed for practical use, and the products are hand-forged by swordsmiths who have inherited two hundred years of casting technology in Longquan, China.
