Santoku vs. Chef’s Knife

Neither knife is better. They’re shaped for two different ways of cutting, and most of the frustration I hear about comes from someone using one with the technique meant for the other. So instead of declaring a winner, let’s figure out which one matches your hands, your board and your habits.

The differences at a glance

How the shape changes the way you cut

Most of the debate comes down to one thing: the curve of the edge.

A chef’s knife has a pronounced belly. Put the tip on the board, lift the handle and bring it down again, and the curve rolls along the board like a rocker. That rocking motion is how many cooks mince herbs and slice onions fast without lifting the knife.

A santoku’s edge is almost flat. Try to rock it and only a short section touches the board; the rest hangs in the air. On the other hand, when you chop straight down, the whole flat edge meets the board at once. Vegetables get cut all the way through, with fewer strings of celery or scallion still connected.

So the question isn’t really “which knife,” it’s “how do you cut?”

• If you rock, you’ll be happier with a chef’s knife.
• If you push or chop, a santoku feels natural.
• If you do both, a chef’s knife (or a Japanese gyuto) handles both styles better than a santoku does.

People on knife forums say much the same thing: the gyuto or chef’s knife is the more versatile blade, and the santoku is better kept for cooks who mostly push-cut.

Task by task: which knife wins

Assuming both knives are sharp, this is how they stack up on everyday kitchen jobs.

Count the rows and you’ll see the pattern. The santoku wins on precise vegetable work. The chef’s knife wins on anything big, hard or bony. Everything else comes down to the cook.

A note for left-handed cooks

Most santokus and chef’s knives are sharpened evenly on both sides, so they work fine for lefties. The catch is with some Japanese knives: a few have slightly asymmetric edges, and D-shaped handles are carved for the right hand. If you’re left-handed and buying a Japanese knife, check for a symmetric (50/50) edge and an octagonal or Western handle.

When a santoku is the better choice

You cut mostly vegetables. Salads, stir-fries, soups, meal prep with lots of dicing. The flat edge and easy control shine here.

You have smaller hands or a small cutting board. A 7-inch blade is easier to manage and less likely to hit the backsplash or hang off the board.

You’re nervous with knives. The shorter blade and rounded tip feel less intimidating, which makes beginners slower and more careful in a good way.

You want something light. A Japanese-style santoku can weigh noticeably less than a heavy German chef’s knife, which matters on long prep days.

When a chef’s knife is the better choice

You rock your knife, or want to learn to. Plenty of cooking instruction teaches the rocking motion, and it needs a curved edge.

You cut big things. Cabbage, butternut squash, pineapple, a whole chicken. Extra length and a sturdier spine help.

You need the tip. Scoring meat, making vertical cuts into an onion, or working around joints all need a pointed tip. America’s Test Kitchen noted in their testing that a santoku’s turned-down tip makes some of these delicate cuts harder.

You want one knife for everything. If you’re only going to own one, the chef’s knife covers more ground. That’s why it’s the main knife in our guide to choosing a kitchen knife.

Same brand, same steel: a fair comparison

To show the difference without brand or steel getting in the way, here are a chef’s knife and a santoku from the same Victorinox Fibrox line.

Same handle, same steel, similar price. The santoku is shorter and lighter, the chef’s knife reaches further and rocks. If you can’t decide, either of these is a cheap way to find out which shape you prefer before you spend more.

What about German vs. Japanese?

Shape and steel are two separate decisions, and people mix them up.

You can buy a German-made santoku (Wüsthof, Zwilling and Victorinox all make them) with softer, tougher steel at around a 20 degree angle. You can also buy a Japanese chef’s knife, the gyuto, with harder steel and a thinner edge.

A German santoku is forgiving and easy to maintain but won’t feel as crisp. A Japanese santoku is lighter and sharper but chips more easily. More on that choice in Japanese vs. German knives.

Handle, weight and balance

Shape gets all the attention, but how a knife sits in your hand decides whether you reach for it every day.

A typical German 8-inch chef’s knife weighs around 8 to 9 oz, with a full tang and a heavy bolster that pull the balance back toward your hand. It feels planted. Some cooks love that heft because the knife falls through food under its own weight.

A Japanese santoku often weighs 6 to 7 oz, and its balance sits further forward, closer to the blade. It feels quick and light, which helps on long prep sessions and for people with smaller hands.

Western-made santokus land in between. A Victorinox or Wüsthof santoku feels like a shorter version of the brand’s chef’s knife.

Pay attention to the handle shape too. If you use a pinch grip (thumb and index finger on the blade, just in front of the handle), the spine and the top of the handle shouldn’t dig into your finger. That one detail causes more complaints than steel or length.

What you get at each price

The takeaway: you can find out which shape you prefer for under $50. Spend more only after you know.

Three myths worth dropping

“A santoku is only for Asian cooking.” The name is Japanese, but the knife has nothing to do with the cuisine. It chops potatoes for a casserole as happily as bok choy for a stir-fry.

“A santoku can’t handle meat.” It handles boneless meat and fish very well. What it can’t handle well is bones, frozen food and long slicing cuts.

“A chef’s knife is always the professional choice.” Many pros use a chef’s knife or gyuto as their main blade because of length and versatility. That doesn’t make a santoku an amateur tool. It’s simply built for a different motion.

Which one makes a better gift?

If you don’t know how the person cooks, a chef’s knife is the safer gift. It suits more styles, and most cooking videos and classes assume one.

A santoku makes a great gift for someone who already owns a chef’s knife, cooks a lot of vegetables, or has mentioned that their big knife feels clumsy. Pair either one with a ceramic honing rod and you’ve given them something they’ll actually use for years. More ideas in Best knife gifts for home cooks.

Try this before you buy

You can test your own cutting style tonight with whatever knife you already own.

Take a carrot and an onion. Cut both the way you normally would, without thinking about it. Then watch your knife hand.

If the tip of the knife stays on the board while the handle goes up and down, you’re a rocker. Go for a chef’s knife or a gyuto.

If the whole knife lifts off the board and comes back down, or moves forward and down in one stroke, you’re a chopper or push cutter. A santoku will suit you, and so would a gyuto if you want extra length.

Then think about what annoyed you. Did the knife feel too long? Did the onion stay connected at the bottom? Did your knuckles hit the board? Those small irritations tell you more about the right shape than any spec sheet.

Can you own both?

Many cooks do, and it’s a sensible setup. A chef’s knife handles big jobs and anything with a bone nearby, and the santoku becomes the quick, light knife for weeknight vegetables.

If budget is tight, though, I’d buy one good main knife and a sharpener before a second main knife. A sharp santoku beats a dull chef’s knife every time, and the reverse is just as true. Our whetstone guide shows how to keep either one sharp.

My pick

For most American home cooks who want a single knife, I’d start with an 8-inch chef’s knife or a 210 mm gyuto. It handles more jobs, and you can rock or push with it.

I’d pick a santoku instead if your cooking is mostly vegetables, if an 8-inch knife feels too big in your hand, or if you already have a chef’s knife and want a lighter second blade. For specific models, see Best chef’s knives under $100 and What is a santoku knife used for?.
