Top Uses for the Santoku Knife

The chef knife, the boning knife, and the paring knife, oh my! There are so many different kitchen knives to choose from, and each has its own special skills. And what about that one with the uniquely shaped blade with the little indentations? That would be the Santoku knife – and it has plenty of uses in the kitchen. 

What is a Santoku Knife and How is it Used?

”Types

A Santoku knife is a Japanese chef knife that serves as a multipurpose tool in the kitchen. Crafted differently than a Western-style chef’s knife, the most noticeable feature is the shape of the blade, often referred to as a “sheep’s foot” although not all modern Santoku knives carry this trait.

Usually measuring about 6 to seven 7 long, the Santoku blade features a curve from the spine to the tip, rather than coming to a point like a traditional chef’s knife. The edge of the blade is usually flat compared to the curved belly of Western chef knives and is designed for the up and down chopping technique often referred to as “push-cutting”. This technique involves lifting the blade between each cut – a much different technique compared to the rock chop method used with traditional chef knives.

The thickness of a Santoku blade is often another notable feature, along with how it's sharpened. Japanese-style blades are traditionally known for being much thinner compared to a Western-style chef’s knife, although you’ll find many variations of the Santoku knife since it’s popularity boom in the early 2000s. For example, the F.N. Sharp Santoku knife (available individually and in both our 6-knife and 3-knife essential setscaptures some of the same traits of a Western-style chef’s knife, including the blade thickness and a slight belly rather than the traditional flat edge.

Traditionally, Japanese chef knives were almost always single bevel, as in the edge is sharpened on one side; however, the double bevel feature commonly seen in Western chef’s knives is also becoming more common in Santoku knives. The difference is that double bevel Santoku blades are usually sharpened at angles ranging from symmetrical 50:50 ratios to asymmetrical 70:30 ratios, while the Western style is almost always 50:50.

Another unique trait on the Santoku blade is the Granton or “scalloped” edge, which refers to the indentations on the face of the blade. The Granton edge is designed to prevent delicate ingredients like fish from sticking to the blade between slices. Just like the Western-style chef’s knife, the Santoku knife is a multipurpose tool with many uses, making it a must for any home kitchen.

How to Use a Santoku Knife

The word Santoku translates as “three virtues,” or “three uses”, and after using a Santoku knife, you’ll find that its design helps it excel at three common kitchen tasks: slicing, chopping and mincing.

Using a Santoku Knife for Slicing

”Using a Santoku for Slicing

A Santoku knife is ideal for slicing cooked and raw meats, fresh vegetables and any other ingredient that requires uniform cuts. If properly sharpened, the blade cuts through any ingredient with ease, and without tearing the flesh of meats or ripping the skin of vegetables. A major advantage of slicing with the Santoku blade is the Granton edge, which makes it much easier to butterfly chicken breasts, pork chops and steaks, and slice through fish without the proteins clinging to the blade.

When it comes to slicing with the Santoku knife, you’ll want to follow some of the same kitchen knife safety rules as working with a traditional chef’s knife, such as keeping your offhand in a claw formation to avoid nicking a finger. To begin slicing, use a quick downward motion while pulling the blade slightly towards you during each cut. It will be tempting to cut straight down without moving the blade towards you, but this can bruise or crush some ingredients rather than cut cleanly, so be sure to practice!

Using a Santoku Knife for Chopping

”Using a Santoku for Chopping

When it comes to chopping with a Santoku knife, the method differs from standard techniques, so you’ll definitely want to practice until you get the hang of it. The flat edge requires you to lift the blade off of the cutting board between each cut, rather than using the rock chop technique commonly used with the Western-style chef’s knife where the tip of the knife stays on the cutting board between cuts.

It’s also a good idea to make sure you have the best cutting board for your knives, All kitchen knives dull with regular use, and the surface you’re cutting on has an important role in prolonging the sharpness of your blades, especially when it comes to the up-and-down chopping technique used with the Santoku.

To begin chopping, first make sure your cutting board is stabilized on a flat surface (placing a damp paper towel underneath your cutting board is a handy trick). Also be sure to stabilize your ingredient – if it’s round, you can cut it in half or take a thin slice off the top or bottom so it lies flat on the cutting board.

Once your ingredient is held in place, align the flat side of the blade against the knuckles of your offhand (fingers should be curled under in the "claw" position). Then begin chopping in a smooth, up-and-down motion while slightly moving the knife forward and lifting the blade off the cutting board between each cut.

As you become more comfortable with the up-and-down chopping technique, you can start chopping even faster by also employing the push-cut technique, which involves pushing the ingredient towards the blade as you chop.

Using a Santoku Knife for Mincing

”Using a Santoku for Mincing

A Santoku knife is one of the best choices when preparing a recipe that calls for minced herbs, garlic, or any other ingredients that involves very fine cuts. Again, that Granton edge will help release sticky garlic from the blade and avoid tearing delicate herbs (which can impact flavor), while the length of the blade and weight of the knife offer greater control between cuts.

As an added bonus, the width of the blade is ideal for scooping up ingredients – just be sure to use the spine of the blade rather than the edge to avoid rolling or chipping the sharpened edge (leaving you with a dull knife).

You'll also want to work with two whetstones, while keeping both moist during the entire process.
