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.
Purple fittings / Damascus steel / Amethyst Nebula
Purple wrapping and a dark violet saya give Amethyst Nebula its color, while the blade stays bright steel. Small gold specks scatter across the scabbard, and a blue-and-white cord breaks up the darker lacquer. Around the guard, a gold-colored rim frames the dragon relief and echoes the smaller golden details on the saya.
The blade
The specification lists Damascus steel, a hamon and a bo-hi groove. It also describes shinogi-zukuri geometry, the blade form with a distinct lengthwise ridge. Small wave engravings sit near the collar. These details occupy different parts of the polished blade, which measures 72 cm and is sharpened and full tang.
The fittings
The deep purple saya has scattered gold specks and cloud-like decoration. A striped blue-and-white sageo ties around it, while purple cotton wraps over black synthetic rayskin on the handle. The copper guard carries dragon relief with a gold-colored rim. Beside it, the iron-alloy habaki has a honeycomb-like geometric pattern.
On this purple katana, the color is on the handle and saya, rather than coating the blade. For an anime design with purple fittings, compare the Enma sword. For a different color on a non-anime model, Emerald pairs green fittings with T10 steel. Our steel guide helps separate those material choices from the color.
In your collection
An ornate dragon display stand and matching saya are included. Keeping the violet scabbard in view lets its speckled finish and striped cord remain part of the arrangement. Allow space for the 105 cm overall length and place the sharpened blade securely.
Keep the steel dry and follow the Care & Maintenance instructions above. Use a soft cloth on the purple lacquer and decorated fittings. Avoid abrasive compounds on the gold-colored details, and keep blade oil off the cotton cord and handle wrapping.
No. The blade has a polished steel appearance. Purple is used on the handle wrapping and lacquered saya, with gold-colored specks on the scabbard.
The specification lists Damascus steel with a visible grain pattern, a hamon and a bo-hi groove. The sword is full tang and sharpened.
A hamon is listed, but the hardening method is not specified for this model. Do not infer clay tempering from the visible line alone. The hamon guide explains the distinction.
It describes a blade shape with a distinct lengthwise ridge. It is a geometry term, separate from the Damascus steel and the decorative colors.
No gemstone parts are listed. Amethyst describes the purple color, and Nebula refers to the scattered, cloud-like decoration on the saya.
No. The handle uses black synthetic rayskin beneath the purple cotton wrapping. Its darker surface shows through the diamond-shaped openings.
Amethyst Nebula is presented as an original Katana Corp design. If you want a specific character's sword, use the manga katana collection to compare those models.
The sharpened katana, matching purple saya and ornate display stand are included. It measures 105 cm overall, with a 72 cm blade, and is sold for collection and display.

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.
