What Makes a Knife Left-Handed or Right-Handed?

Around 10% of people are left-handed — that works out to roughly 700 million people worldwide, and for a long time plenty of tools were designed with only right-handed users in mind. So it's a fair question: is a knife just a knife, or is it better suited to one hand than the other?

The honest answer is reassuring. The handedness of a knife only matters for single-bevel blades, which are ground on one side. The double-bevel knives that make up almost every modern kitchen — and every knife we sell, from santoku to gyuto to nakiri — have a symmetrical edge, so they cut just as cleanly whichever hand you use. This guide explains the difference, so you know exactly when handedness matters and when it doesn't.

What makes a knife left-handed?

Pick up a single-bevel knife designed for a right-handed user and you'll see the blade is ground on one side, with the other side left flat. As your hand naturally turns inwards while you cut, that geometry keeps the cut straight and neat for a right-hander.

Use that same knife in your left hand, though, and the design works against you — it exaggerates the inward twist and the slice wanders. The solution is a left-handed single-bevel knife, ground on the opposite side, so a left-hander gets the same clean cut. Crucially, this only applies to single-bevel blades — more on that next.

Do left-handed knives really work?

For a single-bevel knife, yes — grinding the edge on the correct side genuinely changes how easily and how straight you can cut, and left-handed cooks who switch to a properly-handed single-bevel blade notice the difference straight away.

But this only applies to single-bevel knives. Most Western knives — and all the everyday Japanese knives we sell — are double-bevel, ground evenly on both sides. With those, handedness makes no difference at all: left- or right-handed, the knife performs exactly the same. If your kitchen runs on double-bevel knives, there's nothing special to buy.

Single-bevel knives for left-handed people

Left-handed knives are almost always single-bevel. A single-bevel knife has one flat side while the other tapers towards the cutting edge (some Japanese single bevels also have a slight concave hollow on the flat side). Because only one side is ground, the blade can be taken to an exceptionally keen edge, which is why single bevels are prized for very precise work such as slicing sashimi.

The flat side stays against the food as you cut, while the bevelled side pushes the cut piece away from the blade. On most single bevels the grind is on the right side, for right-handed use; a left-handed single bevel simply has it on the other side. If you're a left-hander buying a single-bevel knife, make sure it's ground for left-handed use. (We don't stock single-bevel knives — every knife in our range is double-bevel and ambidextrous.)

What happens if I use a right-handed single-bevel knife as a leftie?

You won't get far. To make a right-handed single bevel behave, you'd have to hold it in your right hand — awkward and imprecise in your non-dominant hand. Beyond the discomfort, less control over a very sharp blade is a safety issue, so it's worth getting the right tool. Again, this is only a concern with single bevels — a double-bevel knife is comfortable in either hand.

Serrated knives for left-handed people

Serrated knives can be handed too, because the serrations are often ground on one side only — much like a single bevel. If the teeth are on the wrong side for you, the blade won't counter your hand's natural twist and it's harder to cut straight. The only real difference between a handed serrated knife and a single-bevel smooth blade is the toothed edge. Many everyday serrated knives are symmetrical, though, so check before assuming you need a special one.

Is the handle different on a left-handed knife?

The blade grind is the main difference, but handles can vary too. A comfortable handle that gives you good control matters for both comfort and safety. Some contoured handles are shaped for right-handed fingers and feel less natural for a left-hander.

The good news: most kitchen knives, including everything we sell, have symmetrical handles that are comfortable whichever hand you use — another reason a double-bevel knife needs no left- or right-handed version.

Which should I choose: left-handed or right-handed?

It comes down to the type of knife. If you're buying a single-bevel knife — a traditional yanagiba, usuba or deba — match it to your dominant hand: left-handers should choose a left-handed grind, right-handers the standard one. If you're buying a double-bevel knife — which is almost everything, and all we sell — it genuinely doesn't matter. Pick the knife that suits your cooking; it will feel natural in either hand.

Final thoughts

Being left-handed can make some tools awkward, but kitchen knives mostly aren't among them. The one thing that makes a knife left- or right-handed is how the blade is ground, and that only applies to single-bevel (and some serrated) knives.

If you cook with double-bevel knives — which is almost everything in a modern kitchen, and every knife we sell — being left-handed makes no difference at all: the symmetrical edge and handle work just as well in either hand. You only need a dedicated left- or right-handed knife if you're buying a traditional single-bevel specialist such as a yanagiba, usuba or deba. New to Japanese knives?

Frequently asked questions

Do left-handed people need special kitchen knives?

No, not for everyday cooking. Double-bevel knives are ambidextrous. Only single-bevel specialists such as a yanagiba, usuba or deba are made left- or right-handed.

Are Japanese knives left- or right-handed?

The everyday ones we sell — santoku, gyuto, nakiri and so on — are double-bevel and work in either hand. Only traditional single-bevel knives are handed.

How can I tell if a knife is single or double bevel?

Look at the edge: a double bevel is ground symmetrically on both sides, so it meets in the middle; a single bevel has one flat side and one ground side.

Can a left-handed person use a right-handed knife?

With a double-bevel knife, yes — perfectly. With a single-bevel right-handed knife it's awkward and less accurate, so a left-hander should choose a left-handed grind.

Which knife should a left-handed beginner buy?

A double-bevel all-rounder such as a santoku or gyuto. It feels natural in either hand, so you can focus on your technique rather than the tool.
