What steel is used in cherry blossom tsuba tantos?
Updated Mar 2026
The tantos in this collection are forged from manganese steel, a high-carbon alloy known for its durability and its ability to take a refined surface finish. Manganese steel is particularly well-suited to hamon development — the visible temper line along the blade that results from differential heat treatment. During the hardening process, the edge and spine cool at different rates, producing a distinct boundary line that is both a functional signature and a decorative feature. On blue flame hamon pieces, controlled oxidation during polishing enhances this contrast further, creating an iridescent layered effect that shifts in appearance depending on the light angle. For display collectors, this means the blade's visual character is never static.
