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.
“Long, lean, black-forged. The Kurokage line carrying its name in the finish.”
“Long, lean, black-forged. The Kurokage line carrying its name in the finish.”
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.
Sujihiki vs carving knifeEight 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.
Where this blade earns its keep - and where it's the wrong tool.
Warm water + a soft sponge. No dishwasher, ever - the heat warps the handle and the detergent eats the edge.
Wipe to bone-dry the moment it leaves the sink. Standing water is the enemy - even on stainless.
Stainless doesn't need daily oiling. If you're putting it away for more than a month, a thin pass of camellia oil keeps the steel happy.
Daily use: dry and rack. No oil required.
A 1000-grit waterstone every few weeks. Stropping between for a longer life on the edge.
A saya for storage. A stone for the edge. An oil for the steel.
1000-grit waterstone. The workhorse grit for kitchen edges.
Camellia (tsubaki) oil. Food-safe. A thin pass keeps the steel quiet.
“Kurokage 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 60-61. 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. ”

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.
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.
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 60-61 HRC, which is the working sweet spot for Japanese kitchen blades.
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.
