Ray takes its name from the stingray — 鱝 — the same creature whose skin gives the handle its grip, echoed again in the saya’s pattern. This is a mid-range piece presented as a small masterpiece of traditional craft, made for the refined collector and the demanding martial artist who want a blade that performs as well as it shows.
Forging & steel
The blade is forged from high-carbon T10 tool steel, prized for exceptional hardness and cutting ability. Across the edge runs a top-grade hamon — the temper line born in the quench from precise differential heat treatment, where the edge hardens fast while the spine stays tougher. That contrast is what gives a T10 blade both its bite and its resilience: a keen, hard edge backed by a body that absorbs shock instead of shattering. The hamon is not a cosmetic etch but the visible boundary between those two states of the steel.
Fittings
A carved copper tsuba absorbs shock and protects the hands. The saya is dark-blue lacquered wood carrying a ray-skin (stingray) pattern that names the sword. The tsuka wears genuine white shagreen over a copper menuki kit, pinned with two bamboo mekugi for a firm, secure grip.

Is it battle-ready?
Yes. T10’s hardness and the differential temper make Ray a serious cutting blade as much as a display piece. It shares its clay-tempered character with the claw-hamon Emerarudo and the flame-hamon Ikoi, all built on the same hard, edge-holding T10 steel and finished with the temper line each blade is known for.
