Kaiyō means ocean — and this short sword draws like the tide turning. The Kaiyō is a wakizashi cut from T10 tool steel, run through with a bo-hi — the long groove down the blade that lightens the steel and gives it that low, singing draw, like the hush of water pulling back from the shore.

Forging & Steel
The blade is T10 tool steel, a high-carbon tungsten alloy that takes a hard, lasting edge. It carries a genuine hamon — the temper line born in the quench — and the fullered bo-hi that both lightens the blade and sings on the cut. Sharpened and full-tang, it is a working short sword with two real forge features stacked into one entry-level piece.
Mount & Fittings
The mount is fully traditional. A carved gold-plated zinc tsuba guards the collar, a lacquered ebony saya carries a bull-horn kurigata, a gold-plated zinc menuki set rides under the wrap, and genuine shagreen leather covers the tang over bamboo mekugi. Genuine ray-skin and an ebony scabbard at this tier mark the Kaiyō as a blade that has reached above its price for its dress, finishing a sword that earns its ocean name in both look and draw.
Is it battle-ready?
Yes. The Kaiyō is a sharpened, full-tang T10 wakizashi with a real hamon and a functional bo-hi — a working short blade at an entry-level price. Pair it with a katana for a daisho, or compare it with the red-Damascus Wakizashi Ryu and the master-grade Wakizashi Kiku.
