Short answer: most Western chef's knives use a full flat grind — a straight taper from the spine down to the edge with no flat facet left behind it. It slices thin, sharpens easily, and holds up to daily kitchen use. Traditional single-bevel Japanese knives use a chisel grind instead, which gets even thinner but only cuts cleanly in one direction. Almost every production chef's knife also carries a small secondary bevel at the very edge, whatever the primary grind is.
What "bevel" means on a knife
The bevel is the angled section of the blade that gets ground down to a cutting edge. How that angle is shaped — where it starts on the blade, how far it travels, and whether it's on one side or both — is the grind. Grind has nothing to do with steel type or hardness; a full flat grind and a chisel grind can both be made from the same steel at the same hardness and still cut completely differently.
The full flat grind — the standard for a reason
A full flat grind tapers in a straight line from the spine all the way to the edge, so there's no flat, un-ground section left near the back of the blade. Cross-section it and you get a clean wedge. It's the grind on the overwhelming majority of Western-style chef's knives, gyutos included, because it gives a thin, low-friction edge for push cuts and food release, without being so delicate it chips on a cutting board.
It's also the easiest grind to sharpen at home — one consistent angle from spine to edge means less guesswork on a whetstone.
The chisel grind — single-bevel Japanese knives
A chisel grind puts the bevel on one face of the blade only; the other face stays flat. Traditional single-bevel knives like the yanagiba (sashimi slicer) and usuba (vegetable knife) are ground this way, and it lets the edge get thinner than almost any double-bevel grind can manage — which is the point for paper-thin fish slices and precise vegetable cuts.
The tradeoff is handedness. A chisel-ground edge steers slightly during a cut and isn't a general-purpose knife the way a Western chef's knife is. Most home kitchens never need one; most professional sushi and kaiseki kitchens use little else for those specific tasks.
The compound edge you don't see advertised
Look closely at almost any chef's knife, flat-ground or otherwise, and there's a second, steeper bevel right at the cutting edge — usually 1 to 2mm wide. That's the actual edge; the primary grind is what shapes the blade above it. This compound edge is what a whetstone maintains day to day. You are almost never sharpening the whole primary bevel, just that narrow strip.
Which grind for which kitchen
- Home cook, one knife for everything: full flat grind. Forgiving, easy to maintain, cuts almost anything you'll put in front of it.
- Precision fish and vegetable work: a single-bevel chisel grind knife as a second, specialist blade — not a replacement for a flat-ground chef's knife.
- Heavy boning or cutting through joints: look for a slightly thicker flat grind rather than a thin flat grind, which will chip on bone.
How grind changes sharpening and care
A full flat grind is the most forgiving to freehand on a stone because there's only one angle to hold. A chisel grind needs to be sharpened almost entirely on the beveled face, with just an occasional light pass on the flat back to remove the burr — sharpening it like a double bevel knife will ruin the geometry that makes it work. Whichever grind you own, strip food acid and moisture off the blade before it sits, since a thin edge shows the first signs of a chip or a rolled apex faster than a thicker one will.
Questions people ask
Is a thinner bevel always sharper?
Thinner cuts with less resistance, which reads as "sharper" at the board, but thin edges also roll or chip more easily on anything harder than food. Edge retention comes from the compound bevel angle and the steel's hardness, not from how thin the primary grind is.
Does a compound edge mean two separate grinds?
No — it's one primary grind (flat, chisel, whatever) with a narrow secondary bevel ground at a steeper angle right at the edge. Almost every working knife has this whether or not it's mentioned in the listing.
Should I buy a single-bevel knife as my only chef's knife?
Not unless you already know you want one. A single-bevel knife rewards a specific set of cuts and skills; a full flat grind knife will do more things adequately, which is usually what a first or only knife needs to do.
