By purchasing from Katana Corp, you acknowledge and agree that:
For full details, please refer to our Terms of Service.
To maintain your katana's appearance and performance over time, we recommend:
- Regularly wiping the blade with a soft cloth to remove fingerprints and moisture.
- Applying a light coat of choji oil to prevent rust (for carbon steel blades).
- Storing the sword in a dry place, preferably inside its saya.
- Avoiding direct contact with hard surfaces to preserve sharpness and finish.
For more care tips, check our full maintenance guide in the FAQ section.
Every katana we offer carries the essence of centuries-old craftsmanship.
More than just a weapon, the katana symbolizes discipline, honor, and mastery.
Our artisans draw inspiration from traditional forging methods to ensure each blade reflects the spirit of the samurai - strength, precision, and soul.
Owning one is not just about aesthetics - it’s about carrying a piece of that legacy.
This katana is designed to offer a perfect balance between blade and handle.
Its ergonomic tsuka (handle) allows a secure two-handed grip, while the weight distribution ensures smooth, fluid movement.
Sold for collection and display. Handle carefully when placing on a stand or carrying out maintenance.
Navy lacquer and black silk / Seiryu
Seiryu brings together a black silk handle, a deep navy scabbard and white-and-navy cord. The narrow bands near the mouth of the saya add a lighter detail without covering its dark lacquered surface. Its blade is listed as blue-finished T10 steel, with a compact 50 cm overall length.
The blade
The blade specification lists T10 tool steel with a blue finish, full-tang construction and a sharpened edge. The blade measures 33 cm. A genuine hamon is not specified for Seiryu. If you are comparing T10 tantos, check the finish and hamon description separately rather than assuming the steel name means every blade is treated the same way.
The fittings
Black silk wraps over white synthetic rayskin on the handle. An iron guard with relief detail sits beside a brass blade collar. The solid wooden saya has a deep navy finish and a silver-colored accent band, with white-and-navy silk sageo. The black handle and navy scabbard keep the palette dark while the pale cord adds contrast.
In your collection
Seiryu includes its saya and a wooden display stand. Allow room for the listed 50 cm overall length. A lighter background can help separate the navy scabbard from the black handle, with the two-tone cord left visible near the mouth of the saya.
Keep the blade dry and follow the Care & Maintenance instructions above. Avoid abrasive polish on the colored steel finish and lacquered saya. Keep blade oil away from the silk and synthetic rayskin, and dust the decorated fittings gently with a soft cloth.
It is listed as T10 tool steel with a blue finish. The color describes the finish, not a different steel alloy.
No genuine hamon is specified for Seiryu. If that feature matters to you, compare the listed hamon on Aozora or Hagane.
The handle wrapping is listed as black silk. The navy color appears on the saya and in the white-and-navy silk sageo.
The specification lists solid wood with a deep navy lacquered finish and a silver-colored accent band.
It is listed at 50 cm overall, with a 33 cm blade and a 16 cm handle.
No. Seiryu lists a 33 cm blade. The models in our wakizashi collection list 52 cm blades, so compare the measurements as well as the names.
The included set is the tanto, its navy wooden saya and a wooden display stand.
Yes. It is listed as sharpened and full tang. It is sold for collection and display, with careful handling required during cleaning and storage.

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.
