Single vs. Double Bevel Edges Explained

Most Western knives use a double bevel edge without anyone thinking twice about it, but single bevel (chisel ground) edges show up often enough, especially on Japanese-style knives, that it’s worth understanding what actually changes when a blade only has one ground side instead of two.

What a Double Bevel Edge Is

Both sides of the blade are ground down toward the edge, meeting in the center. This is the default for the vast majority of knives: hunting knives, EDC knives, most kitchen knives, tactical knives. A double bevel edge cuts straight, tracking directly along the line you push it through material, and is symmetrical in how it handles regardless of which hand is using it.

What a Single Bevel (Chisel Grind) Edge Is

Only one side of the blade is ground down to the edge; the other side stays flat, unground, all the way to the cutting line. Traditional Japanese kitchen knives (like a yanagiba or usuba) commonly use this, as do some specialty woodworking and food-prep tools. Because all the cutting geometry is on one side, a single bevel edge naturally pulls slightly toward the flat side as it cuts.

Why Single Bevel Edges Are Used

A single bevel can be taken to an extremely thin, precise edge on the ground side without sacrificing strength the way thinning both sides of a double bevel would, which is part of why they’re prized for fine, precise cuts like sashimi slicing. The flat back also acts as a reference surface, useful for certain paring and release cuts against a cutting board or workpiece.

The Handedness Problem

Because a single bevel edge pulls to one side as it cuts, a blade ground for a right-handed user cuts differently, and often uncomfortably, in a left hand, and vice versa. This is a real, practical tradeoff: single bevel knives are typically made handed, and a maker offering them needs to ask which hand the knife is for, something that never comes up with a standard double bevel blade.

Sharpening Differences

A single bevel edge is arguably simpler to sharpen in one sense, there’s only one angle to maintain instead of two, but it also requires occasional flattening of the back (the unground side) to keep the cutting geometry accurate over time, a maintenance step double bevel edges don’t need. Double bevel edges need both sides maintained at a matching angle to stay centered and straight-cutting.

Should a Beginner Try a Single Bevel Blade?

Not as a first project. Getting a clean, flat, consistent single bevel grind is arguably harder to do evenly than a double bevel, since there’s no second side to help visually judge whether the geometry is centered and consistent, and any grinding mistake is fully visible on that one ground face. Build confidence with double bevel grinds first; see Blade Grind Types Explained for the standard grind options to start with.

Is a chisel grind the same thing as a single bevel edge?

Yes, “chisel grind” and “single bevel” describe the same construction: one side ground to the edge, the other side left flat.

Can a single bevel knife be used comfortably by the opposite hand?

Not comfortably for its intended precision use. It will still cut, but the edge geometry pulling the wrong direction makes controlled, precise cuts noticeably harder, which is why handedness is specified when these knives are made or bought.

Do single bevel edges hold up to hard use as well as double bevel edges?

Generally no, the thin, precise geometry that makes single bevel edges excellent for fine slicing also makes them more fragile under lateral stress or harder use than a more robust double bevel edge, which is part of why they’re associated with precision food prep rather than general-purpose or outdoor knives.
