Every blade on this site gets its own trading card - tier-colored, kamon-stamped,
and built around the seven specs that actually predict how the knife behaves on the
line. Steel. Hardness. Edge. Length. Handle. Finish. Origin.

Blade length240 mm
Sujihiki筋引
The double-bevel slicer. A yanagiba's geometry rebuilt for Western kitchens - fish, brisket, prime rib, roasts.
Long enough to draw through a roast in one pass. Narrow enough to glide between bone and meat. The closest a double-bevel knife gets to single-bevel finesse.
Eight flat sides give the blade vertical alignment in your grip. The dominant Japanese kitchen handle - the one professional chefs reach for first.
Ambidextrous. Comfortable in any grip style - pinch, hammer, or finger-tip. The geometry tells your hand where the edge is pointing without looking down.

What VG-10 is good at.
This bladeAverage kitchen knife
VG-10ブイジーテン
+Cobalt-strengthened matrix. Stainless behavior with carbon-like edge retention. Workhorse premium for production blades.
−Slightly less keen at peak than top-tier carbon. Can chip on bone or frozen food.
In your kitchen
A working chef's daily-driver steel. Sharpen every 2-3 weeks in a busy kitchen. Dishwasher? Don't. But forget to wipe it once and it'll forgive you.
Camellia (tsubaki) oil. Food-safe. A thin pass keeps the steel quiet.

A note from us
Why we picked it.
Ethan Founder · Smart Sushi Chef
“Kokushin Sujihiki 240mm is the double-bevel slicer - long-bladed, narrow-spined, built for one long pull. VG-10 holds the edge like carbon but forgives the morning sink, running at HRC 60-62. In the kitchen, that means it carves a roast or fillets a side of salmon in a single stroke without sawing. It sits in our catalog because it earns its keep on a working line, the geometry is honest, and the steel is what the maker said it is. We've held it. That's what gets a knife on this site.

Questions we get
Before you buy.
Is this knife stainless?+
Yes - the chromium content in the steel passes a thin oxide layer over the surface that resists rust under normal kitchen use. You still hand-wash and dry it like any good knife (no dishwasher, no soaking), but you don't need the daily oil-wipe routine a carbon blade needs.
Can I put it in the dishwasher?+
No knife you care about should go in a dishwasher. The heat warps the handle, the detergent dulls the edge, and clattering against other dishes chips the bevel. Hand-wash with warm water and a soft sponge, then dry immediately.
What does HRC 60-62 mean?+
HRC stands for "Rockwell Hardness, scale C" - a measurement of how hard the steel is. Higher numbers mean the steel holds an edge longer but is also more brittle. This knife is 60-62 HRC, which is the working sweet spot for Japanese kitchen blades.
How do I sharpen it?+
Use a Japanese waterstone. 1000-grit for regular sharpening, 5000-grit for finishing. Soak the stone if it needs soaking (most modern Shapton-style stones are splash-and-go), hold the blade at around a 15-degree angle to the stone (a folded coin makes a decent gauge), grind one bevel until you raise a burr along the entire edge, flip and do the other side. Finish with light alternating strokes to remove the burr. Steer clear of pull-through sharpeners - they tear the edge.
Where do you ship?+
We ship from our EU warehouse in Prague. Free across the EU on orders over €80, ~3-5 business days. Outside EU: standard rates apply, customs handled at destination. Tracking on every order.
What if it doesn't feel right?+
30 days, no questions asked. Ship it back, we refund. Damage from misuse (hitting bone, frozen food, dropping) isn't covered - but normal 'this isn't right for me' is. Email office@smartsushichef.com to start.
