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 fittings / quilted saya / Kokuga
Kokuga keeps its color palette simple and lets the textures do the work. The black saya has a repeating diamond pattern, the guard has a rough organic surface, and small gold-colored accents break up the dark handle. Drawn beside the scabbard, the silver-colored blade reveals a wide, rounded line along its edge.
The blade
The blade is 1060 carbon steel, sharpened and full tang. A visible gunome-style line forms rounded lobes along the edge, standing out against the darker reflection of the polished steel. The specification does not confirm how that line was produced, so it is not presented here as verified clay tempering. The blade measures 72 cm.
The fittings
The black saya carries a quilted-looking diamond pattern over its wooden body, with a strap and metal ring near the opening. Black cotton wraps the handle over synthetic rayskin. The zinc-alloy guard has an uneven, rock-like surface, while the brass collar and small gold-colored handle details keep the fittings from disappearing into the dark palette.
For a darker blade as well as dark fittings, compare Full Black. If a specified clay-tempered hamon matters more than the black palette, Imperial lists a choji hamon on T10 steel. The hamon guide explains the difference between a visible line and a confirmed tempering process.
In your collection
Kokuga includes its matching saya and a horn-style display stand. A lighter background makes the dark guard and diamond pattern easier to see. It is sold for collection and display; the strap is part of the fittings, not a reason to treat a sharpened sword as a costume accessory.
Follow the Care & Maintenance instructions above and keep the steel dry. Use a soft cloth around the textured guard and saya, where dust can collect. Avoid soaking the wrapping or strap, and keep blade oil off the cotton and synthetic rayskin.
The fittings and saya are black, while the blade is polished steel with a visible rounded line near the edge. The overall black design does not mean the blade has a black coating.
It describes a line with rounded, repeating lobes. Kokuga shows this shape in its blade photos, but the specification does not confirm a clay-tempering process.
The saya has a textured covering over a wooden body. Its appearance resembles quilted leather, but the covering material is not specified. The attached strap is listed as leather.
It uses 1060 carbon steel with full-tang construction. The blade is sharpened, so keep it secure during display and handle it carefully during maintenance.
No. The handle uses black synthetic rayskin beneath black cotton wrapping. The small gold-colored accents are separate decorative fittings.
No second sword is listed. The set contains the Kokuga katana, its saya and the display stand, rather than a katana-and-tanto pair.
It measures 105 cm overall, with a 72 cm blade and a 30 cm handle. The table above gives the remaining blade dimensions.
Kokuga emphasizes its polished blade, rounded line and quilted-looking saya. Full Black uses a darker blade finish and a different scabbard treatment. Compare their photos and specifications for the individual materials.

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.
