Fully hand-forged in Japan — and no two are alike. This is the kind of piece you almost never see twice… a true one-of-one built for collectors who want something genuinely rare.
The Irodori Series sits in that space where craftsmanship and individuality collide. At its core, you’re getting Aogami Blue #2 carbon steel — a steel known for taking an incredibly fine, aggressive edge and holding it. It sharpens beautifully, performs at a high level, and delivers that raw, precise cutting feel that only a well-treated carbon can give.
But what makes this blade stand out goes far beyond the core.
The entire piece is built around a dark, etched Kurozome finish layered over a hand-forged Rainbow Damascus. You’ll see tones of grey, black and bronze moving through the blade — not as a surface effect, but as real depth in the steel. It shifts in the light, giving the knife a presence that’s hard to capture in photos.
Then there’s the spine — fully exposed through the grind from heel to tip, revealing the Damascus layers in a way you almost never see. It’s a detail that turns the construction itself into part of the design. Raw, intentional, and executed clean.
The grind follows that same philosophy: thicker at the spine, tapering into a thin, precise edge that moves effortlessly through product. It has that solid, forged feel in hand, but with the kind of control and responsiveness you expect from a high-end Japanese blade.
This isn’t just another knife. It’s a fully hand-forged Japanese piece with real character — built for someone who understands both performance… and rarity.
