Single Bevel vs Double Bevel
One of the deepest-sounding distinctions in knives, with a simple practical answer: unless you're a sushi chef, you want a double-bevel knife. Here's why — and what a single bevel really buys.

A knife's bevel is the ground angle that forms the cutting edge. A double-bevelknife is ground on both sides, like a V — nearly every Western and most Japanese kitchen knives, including everything we recommend. A single-bevelknife is ground on one side only, with the other side flat — a traditional Japanese design for specific tasks like slicing sashimi. For almost everyone, the answer is short: buy double-bevel. Here's the why.
What the two grinds do
A double bevel is symmetrical, so it tracks straight through food, cuts equally well for left- and right-handers, and is forgiving to use and sharpen. A single bevelputs the entire cutting angle on one face. That lets it be ground incredibly thin and keen for its intended job — producing paper-thin, flawless slices of fish — and it makes food fall away from the flat side cleanly. But it also makes the knife steerto one side in general cutting, it's handed (a right-handed single bevel is genuinely awkward for a lefty), and it's far fussier to sharpen correctly.
Why double-bevel is right for almost everyone
Single-bevel knives — yanagiba, usuba, deba — are traditional Japanese specialists made for tasks most home cooks never do. They demand practiced technique just to cut straight, and sharpening oneproperly (keeping the flat side truly flat, maintaining the back bevel) is a real skill. A double-bevel chef's knife, santoku or gyuto does everything a home kitchen needs, works for any cook, and is easy to keep keen. This site's lane is exactly those everyday double-bevel knives; single bevels belong to sushi counters, not weeknight dinners.
The nuance: double bevels aren't always symmetrical
One honest complication. Many Japanese double-bevel knives are ground with an asymmetricratio — say 70/30, more steel removed from the right face than the left — to get some of the keenness and food-release of a single bevel while staying usable in both hands. It's still a double bevel; it just isn't a perfect 50/50. This matters when you sharpen: match the factory ratio rather than forcing an even one. Most German knives, by contrast, are a straightforward symmetric V-grind. When in doubt, sharpen to the angle the knife came with.
Practical takeaway
Unless you specifically want to prep sushi and sashimi and are ready to learn the technique and the sharpening, buy a double-bevel chef's knifeand keep it sharp. It's the versatile, forgiving, easy-to-maintain choice, and every knife we rank is one. If you're weighing German against Japanese double bevels, the trade is mapped in Japanese vs German knives.
Questions
Frequently asked
What's the difference between single and double bevel knives?
A double-bevel knife is ground on both sides into a V — symmetrical, versatile and easy to use and sharpen. A single-bevel knife is ground on one side only, with a flat back; it can be extremely keen for slicing fish but steers to one side, is handed, and is much harder to sharpen.
Should I buy a single bevel knife?
Only if you specifically prepare sushi or sashimi and want to learn the technique and the sharpening. For all normal kitchen work, a double-bevel knife is more versatile, works for either hand, and is far easier to maintain.
Are Japanese knives single or double bevel?
Most modern Japanese kitchen knives — gyuto, santoku, nakiri — are double-bevel, sometimes with an asymmetric grind. Single-bevel knives are the traditional specialists (yanagiba, usuba, deba). The everyday Japanese knives you'd buy are double-bevel.
