Santoku vs Chef's Knife: Which One Do You Need?
On this page
Santoku or chef's knife is the first real decision most cooks face when they upgrade their kitchen. Both are all-purpose blades, both handle 90 percent of daily prep, and yet they cut differently enough that one of them will fit your hands and habits better. Here is how to tell which one is yours.
The quick answer
Buy a chef's knife if you want one blade that does everything, including heavy jobs. Buy a santoku if your board is mostly vegetables, you prefer short controlled strokes, or you have smaller hands. The chef's knife is longer and curved for rock chopping; the santoku is shorter, flatter and lighter for push cutting. Neither is better. They reward different cutting styles.
What a chef's knife is built to do
A chef's knife is the Western all-rounder: a long, curved blade with a pointed tip, built to rock through big piles of food. Most run 8 to 10 inches. The curve lets you keep the tip on the board and rock the heel up and down, which turns mincing garlic or herbs into a fast, fluid motion.
That length and weight also mean reach and leverage. Splitting a butternut squash, breaking down a melon, working through a whole chicken: the chef's knife takes these in stride. In our catalog, the Essentials™ stainless chef's knife covers daily work, and the Precision™ Damascus versions run 19.3 cm (7.6 in) and 24.1 cm (9.5 in) for cooks who want more blade.
What makes a santoku different
A santoku is the Japanese all-purpose knife: shorter, flatter, thinner and lighter, designed for clean downward cuts rather than rocking. The name translates as "three virtues," usually read as slicing, dicing and mincing. Most santokus run 5 to 7 inches with a rounded sheepsfoot tip and a nearly straight edge.
The thinner blade takes a keener angle. Western edges are commonly ground around 20 degrees per side, while our Precision™ Damascus santoku is ground closer to 15 with a VG-10 core at HRC 60 ±2. Many santokus, ours included, add Granton dimples along the blade so wet slices of potato or zucchini release instead of sticking.
Head to head: the differences that matter
Five differences decide the match: length, blade profile, tip, weight and cutting motion. Everything else, from handle material to steel finish, is a matter of budget and taste rather than function. Here is the side-by-side view of the five that actually change how you cook.
| Chef's knife | Santoku | |
|---|---|---|
| Typical length | 8 to 10 in (20 to 25 cm) | 5 to 7 in (13 to 18 cm) |
| Blade profile | Curved belly, pointed tip | Flat edge, rounded sheepsfoot tip |
| Weight | Heavier, more leverage | Lighter, more control |
| Cutting motion | Rock chop | Push cut, straight down |
| Best for | Big jobs, dense produce, meat with bones nearby | Vegetables, boneless proteins, thin even slices |
Bottom line: the chef's knife wins on versatility and power, the santoku wins on precision and comfort. America's Test Kitchen reached the same split verdict in its 2023 comparison: both are capable all-purpose knives separated mainly by tip shape, curve and mass.
Rock chop or push cut: match the knife to how you cut
Watch your own hands before you choose: if the tip stays on the board while the heel rocks, you are a rock chopper and want the chef's knife; if the whole blade lifts and drops, you are a push cutter and want the santoku.
The chef's knife's curved belly exists for the rocking motion. The santoku's flat edge exists for the straight drop, and it makes full contact with the board on every stroke, so you get clean cuts without the accordion effect that half-attached herb ribbons betray.
Good to know
A flat edge on a curved-technique cook, or the reverse, is the most common reason a good knife feels wrong. Technique first, then blade shape.
Which one should you buy first?
If you only buy one knife, buy an 8-inch chef's knife: it does everything the santoku does, plus the heavy jobs. That is the honest answer, and it is why the chef's knife anchors our chef's knife collection and most starter sets.
Choose the santoku first instead when at least one of these is true: your cooking is vegetable-heavy, you have smaller hands, or long blades feel unwieldy to you.
Steel makes the second decision easier than it looks. In our 2026 catalog, the entry-level Essentials™ stainless santoku (18 cm blade) is the low-commitment way to try the shape, and the Precision™ Damascus santoku is the same geometry with a harder VG-10 core that holds its edge longer between sharpenings. Whichever you pick, the blade only stays sharp with basic habits; our guide on caring for Damascus steel knives covers the routine that applies to both steels.
Both steels, one shape. From the entry-level 18 cm Essentials™ stainless santoku to the 67-layer Damascus Precision™.

Run through this table before you decide: find the line that sounds most like your cooking week, and the right blade falls out on its own. If two lines apply, the higher one in the table should win, because frequency beats edge cases when you only own one knife.
| You mostly... | Pick |
|---|---|
| Cook a bit of everything, want one knife | 8-inch chef's knife |
| Prep vegetables daily | Santoku |
| Have smaller hands or dislike heavy blades | Santoku |
| Break down squash, melons, whole birds | Chef's knife |
| Want paper-thin, even slices | Santoku |
| Cannot choose | Chef's knife first, santoku second |
FAQ
Should I use a chef's knife or a santoku?
Use a chef's knife when the job needs reach, leverage or a pointed tip: dense produce, large cuts of meat, anything you rock through. Use a santoku for fast, even prep of vegetables and boneless proteins, where its flat edge and light weight give you more control. Most home kitchens end up using both for different boards.
Is a santoku an all-purpose knife?
Yes. A santoku handles slicing, dicing and mincing, which covers the bulk of daily cooking. Its limits are the jobs that want a long, pointed, heavier blade: splitting hard squash, carving around bones, or piercing thick rinds. If those show up often in your kitchen, pair the santoku with a chef's knife.
Can a santoku cut meat?
A santoku slices boneless meat cleanly, and its thin blade excels at even slices of chicken breast, pork loin or fish. What it is not made for is contact with bone or joints; the flat, thin edge and rounded tip give you less leverage and less protection than a chef's knife there. For whole birds or bone-in cuts, switch blades.
Which is better for beginners or small hands?
The santoku is usually the friendlier first knife for smaller hands: shorter, lighter, and the straight edge makes clean cuts without learning the rocking motion. Beginners with average or larger hands do fine starting on an 8-inch chef's knife, which teaches the technique most recipes and cooking videos assume.
What sizes do santoku and chef's knives come in?
Santokus typically run 5 to 7 inches; from our catalog, the Essentials™ santoku has an 18 cm (7 in) blade and the Damascus Precision™ santoku 19.3 cm (7.6 in). Chef's knives run 8 to 10 inches, and our Damascus line offers 19.3 cm (7.6 in) and a large 24.1 cm (9.5 in) blade for bigger boards.
Chef's knife or santoku, the knife you reach for daily is the one that fits how you already cut. Start there, and add the second shape when your cooking asks for it.
