67-Layer Damascus Steel
62 HRC Hardness
Kiritsuke Tip Profile
The Kuro 8.5 Kiritsuke is a single blade forged from 67 true structural layers of VG-10 Damascus steel — not a printed pattern, but a visibly layered cross-section hardened to 62 HRC via vacuum heat treatment. The 8.5-inch Kiritsuke profile replaces your chef knife, slicer, and utility knife in one fluid shape. Full-tang, single-piece construction. Octagonal Japanese rosewood handle. Hand-finished edge. Built in Japan. Built to last a lifetime.
Most chefs own 12 knives and reach for one. The Kuro 8.5 is that knife — the one sharp enough to score a fish, slice a tomato paper-thin, and break down a chicken without ever switching blades. If you cook every day, your knife should be worthy of that. This one is.
Score, slice, and dice in one fluid motion with the Kiritsuke tip. Hold a razor edge through months of daily use — sharpened once a month at most. Feel the balance shift the moment you pick it up: weight centered, handle warm in hand, mind freed to just cook. True 67-layer Damascus construction visible in every cross-section. 62 HRC hardness most production knives never reach. A care ritual that deepens character over time rather than degrading it.
Use it daily — that is what it is built for. Rinse and hand-dry after each session. Hone lightly before heavy prep. Strop or whetstone sharpen once a month to bring it back to first-day sharpness. Store on a magnetic block or in a blade guard to protect the edge between uses.
Every Kuro 8.5 ships with a lifetime craftsmanship guarantee and a 30-day satisfaction promise. If the blade, balance, or finish falls short of what we described, contact us and we will make it right — no hoops, no questions.

When 67 layers of true Damascus steel meet a 62 HRC edge, the results hold up — cut after cut, year after year.
Every component of the Kuro 8.5 Kiritsuke is chosen to deliver professional-grade performance that sharpens your craft, not just your ingredients.
Holds a razor edge longer than standard stainless steel. Japan's benchmark high-carbon core alloy delivers enough flex to resist micro-chipping through daily, demanding cuts.
Structurally layered steel — not printed, not etched. Sixty-six surrounding layers of corrosion-resistant Damascus steel wrap the core, creating the blade's signature flowing grain visible in every cross-section.
Seats naturally in a pinch grip for hours of fatigue-free prep. Hand-carved octagonal geometry and natural anti-slip texture mirror the classic joinery style professional kitchens have trusted for generations.
A hardness level most production knives never reach. Precision vacuum heat treatment brings the blade to 62 HRC so it takes and retains a keen edge through the full demands of daily kitchen use.

“Look, I was ready to send it back I'll be honest, the spine is rougher than I expected at this price. But the edge held through a whole Sunday roast. Grudgingly impressed.”
Marcus T.“Handles brunoise work like it was made for it The flat heel geometry suits my chiffonade technique better than any gyuto I've owned, and the Hagane Kuro holds an edge through a full class without fuss. Not inexpensive, but honest.”
Diana K.“this knife is DIALED IN bro Saved three months for this thing and it was Worth it. Stays FIRE on the line.”
Tyler B.“use it literally every night for dinner I make stir fry and roasted veggie bowls almost daily and this knife just keeps up without me thinking about it. good weight, nothing fussy.”
Rachel O.“Good steel, but the grind is off The VG-10 core is fine and it outcuts my old Wusthof easily, but the secondary bevel is noticeably thicker behind the edge than my Shun Classic ever was. For the price, I expected better geometry coming out of the box.”
Greg N.From effortless prep to blades that last a lifetime, here's what makes the Kuro 8.5 Kiritsuke different.
Every element of the Kuro 8.5 Kiritsuke is engineered to work together — so the knife in your hand feels like an extension of your skill, not an obstacle to it.
Sharp longer, sharpened less
One blade replaces three
Balance you stop thinking about
Built to last a lifetime
The Kuro 8.5 is built to reward daily use — here is how most cooks experience the blade as it becomes the only knife they reach for.
One blade. Forged to replace them all.
One blade. Forged to replace them all.
The 67-layer construction is structural, not decorative. Every cross-section of the blade reveals the actual layering — the same reason the edge holds sharper, longer than knives that just look the part.
The Kiritsuke tip lets you score, slice, and dice in a single fluid motion. Most cooks switch blades out of habit — this knife makes that habit unnecessary.
Vacuum heat-treated to 62 HRC, the Kuro edge stays sharp through daily use and sharpens back to first-day condition in minutes. Softer blades at this price point simply don't hold an edge this long.
The octagonal rosewood handle warms quickly, sits naturally in a pinch grip, and balances the blade so well that the knife stops feeling like a tool and starts feeling like an extension of your hand.
Full-tang, single-piece construction means no weak points at the bolster or handle. A simple care ritual keeps the blade performing like new and deepens its character over years of real kitchen use.

“my prep time is actually cut in half now” I got this before hosting Meena and her boyfriend for the first time and it sliced through everything so cleanly and also the balance just feels right in my hand, which I did not expect at this price point.

“sits perfectly on my magnetic strip” Got this after my promotion and the first thing I noticed is how flat it lays on my knife strip, way flatter than my old one. Told Dave in accounting about it twice already.

“Cuts like nothing I've touched before, but.” The heel geometry bugs me every single session and i've watched enough Ryuichi Sakamoto knife breakdowns to know it's not just me. But i keep reaching for it anyway, which probably says everything.
Carlos R.
“Feels like an extension of my hand.” My grandmother would have loved this knife. Cuts clean, holds an edge.
