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.
T10 steel / deep navy saya / Deep Sea Fang
Deep Sea Fang keeps its strongest color on the scabbard. The deep navy lacquer sits beside a bright polished blade, with black cord adding texture around the saya. Small blue accents show through the dark handle wrapping. The result is a quieter blue katana, with the groove and hamon providing the detail on the steel.
The blade
The blade is specified as T10 tool steel with an authentic clay-tempered hamon. A bo-hi groove runs lengthwise beside the polished surface, separate from the temper line along the edge. The blade is sharpened, full tang and 72 cm long. Look at the angled close-up to see how the groove, broad reflective face and edge line catch the light differently.
The fittings
The saya has a deep blue lacquer finish with black cord bands and a tied black sageo. Black cotton wraps the handle over genuine rayskin, with blue accents visible between the crossings. A dark carved iron guard sits beside a warm brass blade collar. Most of the color stays close to the handle and scabbard, leaving the blade silver-colored.
Deep Sea Fang is a good place to start if you like navy fittings around a polished blade. Azure Spirit puts blue on the blade itself and uses 1095 steel. For another T10 model with a pale saya, compare Shizukesa. The katana steel guide explains the material terms separately from these color choices.
In your collection
The sword comes with its matching saya and a wooden display stand. A light background makes the dark blue lacquer easier to distinguish from the black wrapping. Allow space for the 105 cm overall length and position the sharp blade securely if you display it outside the scabbard.
Wipe the polished blade dry after handling and follow the Care & Maintenance instructions above. Use a soft cloth around the groove and brass collar. Keep blade oil off the cotton and rayskin, and clean the lacquered saya gently around its cord bands.
No. Its blade is silver-colored and polished. The navy color is on the saya, with smaller blue accents on the handle.
The blade is listed as T10 tool steel, with full-tang construction and a sharpened edge. The steel name is not a measured hardness rating for the finished sword.
The product specification lists an authentic clay-tempered hamon. The line along the edge is separate from the lengthwise bo-hi groove.
It is a bo-hi, also called a fuller. The close-up near the guard shows the recessed channel beside the broad polished face of the blade.
Yes. Genuine rayskin is listed beneath the black cotton ito. The blue details visible at the wrapping openings add contrast to the dark handle.
They are cord wrapping around the navy lacquered scabbard. The tied sageo is also black, keeping the textures consistent around the handle and saya.
Overall length is 105 cm, with a 72 cm blade and a 30 cm handle. Its matching saya and a wooden display stand are included.
No. The blade is sharpened. It is sold for collection and display, so take care around the edge when cleaning it or arranging it on a stand.

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.
