Like a shard of volcanic glass, the Obsidian Edge Katana is a study in raw power and dark beauty. Its soul is the unique blackened folded steel blade, where the subtle wood-grain pattern (hada) ripples beneath a deep, dark finish. A golden dragon tsuba emerges from the shadows, a singular point of mythic power against the stark, all-black koshirae. Forged from tough, through-hardened 1095 steel, this is a blade built for resilience and strength, embodying the unyielding nature of obsidian itself.

Why Choose the Obsidian Edge?

  • Unique Blackened Folded Steel Blade: This is the sword's most captivating feature. The blade is forged from 1024 layers of folded steel, then treated with a special blackening process that creates a deep, dark finish while allowing the beautiful, wood-grain-like pattern (hada) to remain visible.
  • Resilient Through-Hardened 1095 Steel: Forged from tough 1095 high-carbon steel, this blade is through-hardened for maximum durability. This process creates a uniformly strong and resilient blade, ideal for standing up to the rigors of cutting practice.
  • Golden Dragon "Ryū" Tsuba: A magnificent golden dragon (Ryū) coils around the alloy tsuba (guard), providing a stunning point of contrast against the sword's otherwise all-black aesthetic. It's a classic symbol of power and strength.
  • Stealthy "Blackout" Aesthetic: This katana features a cohesive "blackout" design, from the gloss-black piano lacquer of the saya to the black synthetic-silk ito and genuine black rayskin (samegawa) of the handle, creating a powerful and intimidating presence.
