67-Layer Damascus Steel

62 HRC Hardness

Kiritsuke Tip Profile

Description

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.

Why the Kuro 8.5 Kiritsuke?

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.

Benefits

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.

Recommended Use

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.

Do you offer a guarantee?

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.

4 Precision-Engineered Materials For One blade built to handle everything

Every component of the Kuro 8.5 Kiritsuke is chosen to deliver professional-grade performance that sharpens your craft, not just your ingredients.

Oregano Oil compound image

VG-10 Steel Core

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.

Black Seed Oil compound image

67-Layer Damascus Cladding

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.

Thymoquinone compound image

Octagonal Japanese Rosewood Handle

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.

Carvacrol compound image

Vacuum Heat Treatment (62 HRC)

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.

Your First Year
with the Kuro 8.5 Kiritsuke

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.

Day 1: First Cuts
  • The edge glides through a ripe tomato without pressure — no drag, no tearing
  • The octagonal rosewood handle settles into your grip like it was fitted for your hand
  • You finish prep faster than usual and find yourself reaching for a second knife that you never actually need
Week 2: The Routine Sets In
  • Long sweeping strokes through proteins feel effortless — thin, even slices every time
  • The Kiritsuke tip handles fine herb work and scoring without switching blades mid-prep
  • Your other knives stay in the block; this one stays on the magnetic strip within reach
Month 3: Total Confidence
  • The Damascus pattern deepens slightly in character — the blade looks more yours every week
  • A single touch-up on the whetstone brings the edge back to exactly where it started
  • You stop thinking about the knife and just cook — the balance does the work for you
Month 6+: Built to Last
  • The edge still shaves cleanly with one sharpen per month at most
  • A few drops of mineral oil every few weeks keeps the Damascus finish vivid and oxidation-free
  • This is the knife you hand down — not replace

5 Reasons Why 5 Reasons the Kuro 8.5 Kiritsuke Outperforms Every Knife in Your Block

One blade. Forged to replace them all.

Real results image
Reason 5

Built to Last a Lifetime — Not a Season

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.

Clinical dosing image
Reason 1

Real Damascus — Not a Printed Pattern

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.

Dual targeting image
Reason 2

One Shape That Replaces Three Knives

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.

Easy to take image
Reason 3

62 HRC Hardness Most Production Knives Never Reach

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.

Clean ingredients image
Reason 4

A Handle That Disappears in Your Hand

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.

What cooks are saying

5.0

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.

worth the pricegreat balance
5.0

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.

worth the pricenice weight to it
5.0

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.
