Hamon (from Japanese, literally "blade pattern") is a visual effect created on the blade by the hardening process. The hamon is the outline of the hardened zone (yakiba) which contains the cutting edge (ha). Blades made in this manner are known as differentially hardened. This difference in hardeness results from clay being applied on the blade prior the cooling process (quenching).
