Blue T10 Steel
The blade is forged from T10 tool steel — tungsten-content high-carbon reaching 60-62 HRC — with a blue finish. T10 provides premium-tier hardness and edge retention: the same grade used on our Kumo, Shirokuro, and Ouryu katana. The blue finish over the T10 gives the Seiryu tanto its visual connection to the Azure Dragon — the water deity whose domain is oceans, rivers, and rain. When drawn from the navy saya, the blue blade continues the color palette from scabbard through steel.
Seiryu — Azure Dragon of the East
Seiryu (青龍) is the Azure Dragon — one of the Four Celestial Guardians (Shijin 四神) in Japanese and Chinese mythology. Seiryu guards the eastern direction, governs the element of water, rules the season of spring, and commands storms. Japanese dragons differ from Western firebreathers: they are water deities, bringers of rain and prosperity, benevolent unless provoked — then unstoppable. Samurai carried dragon-themed blades as talismans for protection, particularly in maritime or rain-season contexts. The Seiryu tanto carries that guardian mythology on a blade small enough to keep close.
Navy Saya with Silver Accent
The saya is deep navy lacquered solid wood — darker than the Aozora's blue, closer to midnight. A silver accent band wraps the koiguchi area, breaking the monochrome navy with a metallic flash that references the dragon's scales catching moonlight. The white-and-navy silk sageo provides the bicolor cord accent. The Seiryu tanto saya reads as formal and serious — the navy-and-silver palette associated with naval authority and ceremonial rank across multiple cultures.
Black Silk Ito
Black silk ito wraps the handle — the premium wrapping material, here in black rather than matching the navy saya. The contrast is deliberate: the dark handle grounds the composition, preventing the navy-silver palette from becoming too uniform. White rayskin diamonds flash through the black crossings, providing the same light-against-dark rhythm found on the Yami and Hagane. The Seiryu joins them as the third black-silk tanto — each using the same material for a different aesthetic purpose.
Display & Collection
Ships with a reddish wooden stand. The Seiryu pairs with our dragon-themed katana — the Ryujin (3D dragon tsuba), Ginkai (engraved dragon blade), or Ouryu (twin dragon guard) — for a dragon mythology display spanning katana and tanto. In the seven-tanto lineup, the Seiryu occupies the mythological position: the only tanto named for a specific deity. Browse our collection for full dragon pairing options. The navy saya and silver accent ensure the tanto holds its own beside full-size katana.
Frequently Asked Questions
Who is Seiryu?
Seiryu (青龍) is the Azure Dragon — one of the Four Celestial Guardians in Japanese mythology. He guards the East, controls water and weather, rules the spring season, and commands storms. Dragon-themed blades were carried as talismans for protection.
Does this tanto have a hamon?
No. The blue T10 blade does not feature a visible hamon. For a tanto with genuine hamon, see our Aozora (T10 with clay-tempered hamon) or Hagane (Damascus with clay-tempered hamon).
Is this Seiryu tanto sharp?
Yes. The blue T10 tool steel blade is hand-sharpened and functional. Handle with care, store in the saya, and check local regulations before ordering.
What does Seiryu mean?
Seiryu (青龍) means "Azure Dragon" — the blue-green dragon deity that guards the eastern direction in Japanese mythology and commands water, rain, and storms.
How does this compare to the other tanto?
The Seiryu is blue T10 with black silk ito and a navy-silver saya — the mythological entry. No hamon, but premium silk wrapping and the deepest navy saya in the lineup. For hamon, choose Aozora or Hagane. For visual drama, choose Enzan or Aoto. For darkness, choose Yami. For art, choose Shirayuki. The Seiryu is for dragon collectors.

Excellent
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.
