Frequently Asked Questions

What is clay tempering?
Clay is applied to the blade in patterns before heat treatment. Covered areas cool slowly (softer spine); exposed areas cool rapidly (harder edge). The boundary creates the visible hamon line.
Why is clay tempering special on tanto?
The compact scale concentrates the hamon at a viewable distance. The temper pattern is immediately visible in detail without magnification.
What steels produce the best hamon on tanto?
T10 and 1095 produce the most active, vivid hamon patterns due to their high carbon content.
Is clay tempering purely aesthetic?
No. It creates functional differential hardening: hard cutting edge plus flexible spine. The hamon is the visible evidence of this structural engineering.
