Santoku vs Chef’s Knife: Which One Should You Buy?
Both knives cover most everyday cooking. The practical differences are the shape of the edge, the length of the blade and the cutting motion each one suits. This guide compares them side by side and gives a simple way to decide.
Short answer
- Choose a santoku if you mostly prepare vegetables and boneless proteins, work on a small board, and cut with a straight push.
- Choose a chef’s knife if you rock the blade while chopping, cut large roasts or big squash, or want a longer reach.
- Neither cuts bones or frozen food well. That job belongs to a cleaver or boning knife.
Side-by-side comparison
| Feature | Santoku | Chef’s knife |
|---|---|---|
| Origin | Japan, 1940s | European tradition, in German and French styles |
| Typical blade length | About 15 to 18 cm (6 to 7 in), some to 20 cm | About 20 cm (8 in); models range from 15 to 36 cm |
| Edge profile | Flat or nearly flat | Curved belly; German style curves along the whole edge, French style is straighter then curves up to the tip |
| Tip | Rounded sheep’s foot | Pointed |
| Build | Generally shorter, thinner and lighter | Generally longer and heavier |
| Cutting motion | Push or straight-down slicing | Rocking, chopping or slicing |
Shape and cutting motion
The flat edge of a santoku lands on the board along most of its length. Push forward and down and the food is cut in one stroke, which feels controlled and works well for vegetables and slicing. The tradeoff is that there is little curve to rock on, so the knife supports a limited rocking motion compared with a European blade.
A chef’s knife has a curved edge. The tip can stay on the board while the heel lifts and drops, which many cooks use to mince herbs and chop quickly. The same curve also lets the knife work through bigger pieces with a long slicing stroke.
Chef’s knife Curved edge, pointed tip
Santoku Flat edge, rounded tip
Bunka Flat edge, angled tip
Length and control
A 7-inch santoku is about an inch shorter than the standard 8-inch chef’s knife. That makes a difference on a small board, in a crowded kitchen and for anyone with smaller hands, because there is less blade to manage. A longer chef’s knife gives reach through large cuts of meat or a big cabbage without sawing. If you are not sure, a 7- or 8-inch blade is the sensible middle for both styles.
Steel and edge angle
Santoku are commonly made from harder steel and ground to a more acute edge than European chef’s knives. A narrower angle cuts with less force but is easier to chip; a wider angle is more forgiving of rough use and gives up a little sharpness. Sources quote anything from about 8 to 15 degrees per side for Japanese-style double-bevel knives, and 10 to 15 is a common range. In practice that means a santoku rewards careful use: no twisting in hard foods, no bones, no frozen items. A chef’s knife with a wider edge tolerates more abuse.
These are tendencies, not rules. Always check the maker’s steel and hardness figures for the specific knife you are considering. For an example of how to read them, see AUS-10 steel explained.
Task by task
| Task | Santoku | Chef’s knife |
|---|---|---|
| Slicing vegetables | Flat edge and thin blade cut straight through | Works well; slightly thicker blade |
| Mincing herbs and garlic | Short chops with the tip near the board | Rocking cut is quick once learned |
| Boneless meat and fish | Clean slices with a thin blade | Long blade slices large cuts in fewer strokes |
| Large roasts and big squash | Limited by blade length | More reach and weight |
| Bones, frozen food | Avoid | Avoid; use a cleaver or boning knife |
How to decide
- Think about how you cut now. If you rock the knife, start with a chef’s knife. If you push straight down, a santoku will feel natural.
- Look at your board and your hand size. Small board or small hands favour a santoku or a 6- to 7-inch blade.
- Think about the food. Mostly vegetables, fish and boneless meat suit a santoku. Regular roasts, whole poultry or large squash favour a chef’s knife.
- Pick the one that feels balanced in your hand. A knife you enjoy holding is the one you will use and keep sharp.
The two overlap enough that one good knife of either type can run most home kitchens. A second knife mostly adds a different feel or extra reach rather than new abilities.
Sharpening and care
Both are cared for the same way: hand wash, dry immediately, store the edge protected, hone regularly and sharpen when honing stops working. The difference is the angle you sharpen to, so check the manufacturer’s recommendation. The sharpening guide explains the angle and the steps, and honing vs sharpening explains what to do between sessions.
Frequently asked questions
Can a santoku replace a chef’s knife?
For most everyday jobs, yes: vegetables, herbs, boneless meat and fish. It is less suited to very large roasts, big squash and bones, where a longer chef’s knife or a cleaver does better.
Is a santoku good for beginners?
Many beginners find the shorter blade and flat edge easy to control for straight cuts. If you already use a rocking motion, a chef’s knife may feel more natural.
Which is easier to sharpen?
Neither is hard. Both are usually double-bevel and sharpen on a whetstone. The main difference is the edge angle, so follow the maker’s recommendation.
Is a santoku better than a chef’s knife?
Neither is better in every case. A santoku favours push cuts and light handling, while a chef’s knife favours rocking cuts and reach. Match the knife to how you cook.
