Our differentially tempered (hardened) steel katanas are made by popular request for various purposes. Mostly, it is for those looking for an unetched hamon blade for display purposes and occassional cutting.

We still prefer and recommend the use of through tempered blades for cutting as it is more durable and more predictable, but understand the desire of the market for a true differentially tempered blade... especially for collecting purposes.

Our differentially hardened blades are made by hand claying, scraping the hamon, then packing the spine of the blade for a second temper and quenching... and we do not etch over the natural hamon. This results in a very attractive and subtle hamon with alot of activities at its border.

Differentially Hardened 9260 - "Kaze" Katana

Sale Price: $329.99
Regular Price: $599.99

The Kaze (Wind) is the result of many popular requests for a clay tempered (hardened) blade using our 9260 Silicon Alloy Spring Steel. The blade body of the Kaze is a hand clayed and differentially heat treated 9260 silicon carbon spring steel. It is finished with a replica of an antique blackened cast steel tsuba submitted to us. This steel is stronger than our Kanbai katana, but does not have the same resiliency of the through hardened 9260. The gain from the clay hardening is that the blade has a smooth and elegant natural hamon (9260 does not generate the same hamon as the Kanbai katana).
