Product Details

This T10 steel katana features a clay-tempered blade with a striking blue finish and white lightning-streak hamon lines that run along the full 28.34-inch nagasa. The tempering process achieves 60 HRC edge hardness, and the blue-toned surface gives the steel an electrified, storm-like appearance that sets it apart from standard finishes. For those drawn to distinctive Blue Katana designs, this one delivers exceptional visual impact.;

The 10.62-inch tsuka is wrapped in black leather ito over white PU samegawa in a traditional diamond pattern. Gold and silver accent menuki sit beneath the wrap, adding subtle pops of color between the black and white layers. The grip feels substantial and well-balanced against the blade weight.

A sculpted alloy dragon tsuba serves as the hand guard, rendered in dark blue-black tones with layered detail across the dragon's scales, horns, and open jaw. The dimensional metalwork catches light at multiple angles and anchors the sword's mythological design theme.

The hardwood saya is finished in piano lacquer and wrapped in a vivid blue lightning-print leather that mirrors the blade's storm motif. At 29.52 inches, it fully houses the nagasa and features a matching blue sageo cord. The koiguchi transitions from the saya's electric blue into the dragon tsuba seamlessly.

Overall length reaches 40.15 inches at 2.53 lbs, making this a full-size katana with real presence on a wall mount or display stand. The wing-shaped kashira pommel cap - finished in layered blue-black with fine ridged detail - completes the design. Among Steel Katana collectibles, this piece stands out for its cohesive storm-dragon theme from tip to pommel.

The sword and everything about the sword is absolutely beautiful. Peride my only complaint is that the scabbard the pairs to be made of thick cardboard or some kind of cheap wood if it was made out of a more solid or sturdy material. I would be 5 staring this all day long. .
I do have another one coming, so we'll see what that 1 looks like.
