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.
Black and cream design / Obsidian
A black blade and cream wrapping give the Obsidian katana its sharp contrast. The honeycomb-patterned collar adds a warm bronze detail, while an illustrated cream saya introduces purple and red tones that are easier to see with the sword sheathed.
The blade
The blade is made from T10 tool steel with a black finish, a sharpened edge and full-tang construction. Obsidian is the model name, not the blade material. The gallery shows how light picks out the dark surface and curved point. Its 72 cm blade makes a strong contrast against the cream handle and scabbard.
The fittings
A bronze collar with honeycomb openwork sits between the blade and the glossy black copper-alloy guard. Cream cotton wraps the handle over black imitation rayskin, leaving a row of dark diamonds visible. Matching cream cord and warm metal fittings connect the handle to the illustrated wooden saya.
With the blade drawn, black steel and the honeycomb collar take the attention. With it sheathed, the cream saya brings its purple-and-red illustration forward. The design has a different balance from an all-black katana: the pale wrapping and artwork remain visible even against a dark display background.
In your collection
The wooden display stand is included with the katana and saya. Place the scabbard so its illustration faces outward, with the blade above it and the collar clear of the stand supports. Allow for the full 105 cm length and keep the sharp edge secure when arranging the display.
Keep the carbon-steel blade dry and follow the Care & Maintenance instructions above. Avoid abrasive polish on the black finish and illustrated saya. Handle the cream cotton with clean, dry hands and keep blade oil away from the wrapping and cord.
No. The blade is T10 tool steel with a black finish. Obsidian is the name of this model, not a claim that the blade is made from volcanic glass.
No. Light and viewing angle still affect its appearance, as the gallery shows. The finish is black, but we do not describe it as completely non-reflective.
Yes. It has a sharpened steel edge and full-tang construction. It is sold for collection and display and should be handled carefully during maintenance or display changes.
The round black guard is copper alloy. The honeycomb-patterned blade collar, called the habaki, is bronze.
The black rayskin under the cream cotton is imitation. The cream outer wrapping is cotton, with a matching cream scabbard cord.
The cream lacquered wooden saya carries a purple-and-red illustration with figures and lettering. The close-up shows the artwork more clearly than the full sword photo.
It measures 105 cm overall, about 41 inches, with a 72 cm blade and a 30 cm handle. The specification table includes blade width and thickness as well.
Yes. The illustrated cream saya and wooden display stand are included with the Obsidian katana.

Customer reviews
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.
