Santoku vs chef knife: which shape to buy first

How the two shapes differ

A Western chef knife and its Japanese cousin the gyuto share the same basic shape: a long blade, a gentle continuous curve from heel to tip and a sharp point. The curve lets you rock the blade, keeping the tip on the board while the heel rises and falls, and the length lets you draw long slices through roasts or melons in one stroke. Our gyuto explainer covers that shape in detail.

A santoku is shorter and taller in proportion, with a flatter edge that curves up only near the front, and the spine drops down to a rounded sheep's foot tip. The flat edge suits push cutting, where you drive the knife forward and down, and up-and-down chopping, where the whole edge meets the board at once. The rounded tip is less useful for fine point work but less likely to catch. See what a santoku is used for.

Matched pairs: spec table

These four knives come from two lines, so steel, handle and edge stay constant within each brand. Specs are taken only from the listings.

Rocking vs push cutting

The cutting motion you already use matters more than any spec. Many US home cooks learned to rock a chef knife, especially for mincing herbs and garlic. The curved belly of an 8-inch chef knife makes that easy. A santoku has little belly, so rocking feels choppy and the edge slaps the board.

Cooks who push cut or chop straight down often find the santoku more natural. The flat edge contacts the board along its length, so a stack of scallions or a pile of sliced carrots separates cleanly with fewer incomplete cuts. The Wusthof IKON santoku listing notes it is thinner than the traditional chef knife with a straighter edge, which is exactly the trait that suits this style. Our guide on how to cut with a chef knife shows both motions.

• Mostly rock-chop and mince: chef knife.
• Mostly push cut and chop vegetables: santoku.
• Slice large roasts, melons, cabbage: chef knife for the extra inch.
• Small board or cramped counter: santoku.

Length, tip work and the one-knife kitchen

The extra inch of an 8-inch chef knife matters most on big items: halving a large squash, slicing a brisket or cutting a whole cabbage. It also gives more room to rock without the heel hitting your knuckles. The pointed tip handles fine work such as scoring, trimming silver skin or opening a pepper, which reduces the need for a separate paring knife.

A 7-inch santoku is easier to control for many people, especially those with smaller hands, and it fits on smaller boards. The tall blade gives good knuckle clearance and works as a scoop to move food into a pan. What it gives up is reach and the fine point. If you are building around one knife, our chef knife size guide and how many knives you need pages help you plan the rest.

Japanese vs German versions of each shape

Both shapes come in Japanese and German styles, and that choice changes the feel as much as the shape does. The Shun Premier pair uses VG-MAX steel and a 16-degree edge for a thin, light, very sharp blade that needs gentle care. The Wusthof Classic IKON pair uses 58 HRC stainless with a double bolster, so it is heavier and more forgiving of rough use.

Interestingly, Wusthof gives its IKON santoku a 10 degree edge, sharper than the chef knife in the same line, because the santoku is meant for finer vegetable work.

Frequently asked questions

Is a santoku better than a chef knife for vegetables? For push cutting and chopping vegetables a santoku often feels faster and cleaner thanks to its flat edge. A chef knife still handles vegetables well, and it is better for rock-mincing herbs and slicing large produce.

Can a santoku replace a chef knife? For many home cooks, yes. It covers everyday slicing, dicing and mincing. You give up some length for big items and the pointed tip for fine work, so you may want a petty knife alongside it.

What size santoku and chef knife should I buy? Santokus are most commonly 7 inches, about 180 mm. For chef knives, 8 inches or about 210 mm is the usual home size, with 240 mm for cooks who like more reach.

What about a gyuto vs santoku? A gyuto is the Japanese chef knife, so the same logic applies. See our dedicated gyuto vs santoku comparison for Japanese-only picks.
