K120C powder steel is a type of high-quality steel used in the manufacture of Japanese swords and other cutting instruments. It is also known as fine cut powder steel and is characterized by high hardness and corrosion resistance .
This type of steel is produced by a special powder metallurgy process that involves melting iron powder and other metals at high temperatures and then rapidly quenching in water. The result is a high-quality steel with a fine, uniform grain structure that gives it excellent cutting ability and wear resistance .
K120C powder steel is one of the most widely used materials in the manufacture of Japanese swords and is considered a standard of quality in the sword-making industry. Its use in Hanwei's Tori Tanto is proof of the high quality and craftsmanship of this piece.
