Specifications
Handcrafted Raisenga Katana in T10 tool steel — a straight-blade design with a royal blue section featuring white wind-slash patterns and a chrome shield tsuba with sculpted dragon relief. Full tang, sharpened. Chrome fittings throughout: shield-shaped tsuba, sculpted habaki, beast-head pommel. Tan cotton ito handle. Dark anthracite textured saya. Includes red wooden display stand. T10 tungsten steel, chrome hardware, straight geometry — this blade breaks every convention and earns its place doing it.

T10 Tool Steel — Premium Hardness
The blade is forged from T10 tool steel — a tungsten-content high-carbon steel that reaches 60-62 HRC after heat treatment. T10 offers superior edge retention and hardness compared to the 1060 carbon steel used in most of our catalog. The extra hardness matters on a straight blade like the Raisenga katana: straight geometry concentrates force differently than curved katana, and the steel needs to hold up under that stress profile. T10 is the same grade used on our Sekiro and Jin Sakai swords — the premium tier of our lineup.
Blue Wind Pattern — Storm on Steel
A royal blue-violet section near the habaki carries white wind-slash patterns — jagged, branching lines that suggest lightning or wind streaks cutting across a storm sky. The pattern occupies the upper portion of the blade where it meets the chrome fittings, framing the decorated zone between polished steel and chrome guard. The Raisenga katana name (雷旋牙 — "Thunder Spiral Fang") references the elemental energy the pattern captures: concentrated atmospheric force frozen mid-strike.
Chrome Dragon Tsuba & Beast Pommel
The tsuba breaks from the circular or oval shapes found on traditional katana. It is shield-shaped — a tapered chrome disc with a sculpted dragon or beast in high relief on the face. The chrome finish gives the guard a mirror-like reflectiveness that contrasts with the matte blue blade section. At the opposite end, the pommel carries a matching chrome beast head, bookending the handle with sculptural metalwork. The chrome hardware positions the Raisenga closer to fantasy sword design than traditional Japanese — a deliberate choice for a blade whose straight geometry already departs from the curved katana silhouette.
Straight Blade — Jian-Influenced Geometry
The blade is straight, not curved. This geometry references the Chinese jian rather than the Japanese katana — a deliberate design crossover. Straight blades thrust differently, cut differently, and balance differently than curved ones. The Raisenga katana sits at the intersection of two sword traditions: Japanese T10 steel and forging techniques combined with Continental Asian straight-blade design. The result is a hybrid that doesn't fully belong to either tradition — which is exactly the point.
Display
Ships with a red wooden stand. The chrome-blue-tan palette reads as futuristic fantasy rather than historical recreation, making the Raisenga a natural fit for gaming setups, fantasy collections, and modern display cases. The straight blade and shield tsuba distinguish it immediately from every curved katana on the same shelf. Pair with the Cyberpunk Katana for a tech-forward display or with the Sekiro for a T10 steel comparison.
Frequently Asked Questions
Why is the blade straight?
The Raisenga uses a straight jian-influenced blade geometry rather than the traditional curved katana shape. This is a design choice that references Chinese sword traditions while using Japanese T10 steel and forging methods. Straight blades offer different cutting and thrusting characteristics than curved ones.
What is T10 steel?
T10 is a high-carbon tool steel containing tungsten, which increases hardness and wear resistance. After heat treatment it reaches 60-62 HRC — harder than 1060 carbon steel (typically 56-58 HRC). T10 holds a sharper edge longer and is considered a premium-tier sword steel.
Is this Raisenga katana sharp?
Yes. The T10 tool steel blade is hand-sharpened and functional. Handle with care, store in the saya, and check local regulations before ordering.
What is the tsuba shape?
The tsuba is shield-shaped rather than the traditional circular or oval form. It features a sculpted dragon or beast in chrome high-relief — a fantasy-influenced design that matches the blade's hybrid aesthetic.
What does Raisenga mean?
Raisenga (雷旋牙) translates roughly to "Thunder Spiral Fang" — a name referencing concentrated elemental force. The white wind-slash patterns on the blue blade section visually capture that storm energy.

Excellent
Good sword, small issue on arrival
Saya mouth was slightly loose when I got it, fitting tape sorted it. Balance is great though. People at my dojo always ask about it.
Way better than I expected
Hamon is clean, handle wrap tight, saya closes solid. Came in a wooden box. No complaints at all for the price.
Got it as a gift, he was speechless
Bought for my boyfriend who does iaido. He said the fit and finish were legit. I knew nothing about swords, site made it easy to pick.
Nice blade but took 2 weeks to arrive
Damascus looks great. Shipping to Portland took forever and tracking was dead for a week. Quality is there, logistics need work.
Third order, still no complaints
Ordered three times over two years. Always well packed, matches the photos. Support replied same day. Will keep coming back.
