Santoku Knives: What They Are, How They Work, and Whether You Need One

A santoku knife is a Japanese all-purpose kitchen knife, typically 6 to 7 inches, with a wide, flat blade and a blunt tip. The name means "three virtues" in Japanese, referring to its suitability for meat, fish, and vegetables. It handles many of the same tasks as a chef's knife but with a different blade geometry that suits different cutting techniques. If you like the push-cut motion rather than the rocking chop, or if you find an 8-inch chef's knife feels too long and awkward, a santoku is worth serious consideration.

This article covers exactly how the santoku differs from a chef's knife, which tasks each excels at, what to look for in a quality santoku, and which models are worth buying.

Santoku vs. Chef's Knife: The Real Differences

The comparison matters because these are the two knives most home cooks consider as their primary blade.

Blade Profile and Length

A chef's knife typically has a pronounced curve from heel to tip, designed for a rocking motion where the tip stays on the board and you raise and lower the heel. An 8-inch chef's knife is the standard.

A santoku has a much flatter edge. The blade runs nearly straight from heel to tip, with just a slight curve, then drops sharply to a blunt, sheep's foot tip. This flat profile means the entire edge makes contact with the cutting board at once during a push-cut, which is more efficient for certain styles of chopping.

The santoku is also shorter, usually 6 to 7 inches, versus the standard 8 inches for a chef's knife. Shorter means more maneuverable for some cooks, though it also means you can't slice a large roast in one clean stroke the way you can with a longer blade.

Cutting Technique

The rocking chop suits a chef's knife. You keep the tip on the board, raise the heel, and use a rocking motion to chop through food. This is efficient for large-volume chopping and works well with the curved German-style blade.

Push-cutting suits the santoku. You lift the blade entirely off the board and push it straight down and slightly forward through the food. This produces clean, even cuts on vegetables and fish, without the forward rocking motion that can pull food unevenly.

Neither technique is better universally. Many experienced cooks use both interchangeably. The question is which feels more natural to you.

The Granton Edge

Many santoku knives feature a granton edge, a series of oval hollows ground into the side of the blade above the edge. These hollows create air pockets that reduce suction between the blade and food, preventing thin slices from sticking to the blade.

It helps, but it's not magic. A sharp blade with a granton edge is noticeably better for slicing thin cuts of fish or thin vegetable rounds. But the hollows don't eliminate sticking entirely, and a well-made non-granton santoku still performs well.

What the Santoku Does Better Than a Chef's Knife

Slicing thin: The flat edge and Japanese steel sharpness produce exceptionally thin, even slices through vegetables, fish, and boneless meat. If you make cucumber ribbons, paper-thin radish slices, or precise cuts for a presentation, the santoku's geometry is an advantage.

Vegetable prep: The flat edge makes full contact with the board on each stroke, which is efficient for dicing onions, brunoise cuts, and fine chopping where consistency matters.

Shorter cutting tasks: For most home cooking where you're not breaking down a whole chicken or cutting through a large roast, the 6 to 7-inch length is plenty and more maneuverable than an 8-inch blade.

Smaller hands: Many cooks with smaller hands find the santoku's shorter length and lighter weight easier to control for extended prep sessions.

What a Chef's Knife Does Better

Long slicing strokes: An 8-inch chef's knife lets you slice through a roast or a large piece of fish in one clean motion. A 7-inch santoku requires more strokes.

Heavy-duty chopping: The rocking chop with a heavier chef's knife is efficient for large-volume prep. The santoku's push-cut method requires more arm motion for the same task.

Versatility on large items: Butternut squash, large cabbages, and other bulky vegetables are easier to handle with a longer blade.

Tip work: The pointed tip on a chef's knife lets you score meat, pierce packaging, and do detail cuts. The blunt santoku tip is less useful for these tasks.

What to Look for in a Santoku

Blade thickness: Thinner is better for slicing. Japanese-made santokus are typically thinner than German equivalents, producing cleaner cuts.

Steel hardness: Same rules as any Japanese knife. VG-10 at 60 HRC is the reliable mid-range. Softer steel (under 58 HRC) means the edge dulls faster.

Edge angle: 15 to 17 degrees per side for Japanese-style, 20 degrees for German-style. The Japanese angle is sharper but requires whetstone care.

Handle fit: This matters more with a santoku than a chef's knife because the shorter blade puts more emphasis on hand position relative to the handle. Hold it before buying if possible.

Weight: Santokus range from around 120 to 220 grams. Lighter knives reduce fatigue during long sessions. Heavier knives provide more force for dense vegetables.

The Top Santoku Knives Worth Buying

Victorinox Fibrox Pro Santoku 6.5-inch ($45 to $55): The best budget option. Stamped German stainless, excellent balance, the Fibrox textured handle that works well wet or dry. A step up from most budget santokus.

MAC Superior Santoku 6.5-inch ($85 to $100): The step-up buy. High-carbon stainless steel, thinner and sharper blade profile than the Victorinox, with a more refined feel. The granton edge is standard. A great daily driver for anyone committed to Japanese-style prep.

Shun Classic Santoku 7-inch ($130 to $160): VG-MAX steel at 61 HRC, Damascus cladding, D-shaped walnut handle. Beautiful knife with strong edge retention. The best santoku for someone who wants Japanese aesthetics alongside the performance.

Wusthof Classic Santoku 7-inch ($130 to $150): German-style construction in santoku form. Forged X50CrMoV15 steel at 58 HRC, full bolster. Heavier and more durable than Japanese equivalents. The choice for cooks who want a santoku that handles German knife care.

Tojiro DP Santoku 6.7-inch ($60 to $80): VG-10 steel at 60 HRC in clean, simple construction. The best value among Japanese-made santokus.

Do You Need Both a Santoku and a Chef's Knife?

Probably not. Most home cooks do fine with one or the other. The santoku handles the same tasks as a chef's knife for everyday cooking with a different motion. The chef's knife handles longer slicing tasks and heavy-duty work slightly better.

Where owning both makes sense: you already have a good chef's knife and want a dedicated Japanese-style blade for vegetable prep and fish work. Or you cook for two different people who prefer different cutting styles.

Caring for a Santoku

Same rules as any Japanese-style knife:

Whetstone for sharpening: Set the angle to match the factory bevel (usually 15 to 17 degrees for Japanese, 20 for Wusthof). Pull-through sharpeners set the wrong angle.

Ceramic honing rod: Standard steel rods are too hard for HRC 60+ steel.

Hand wash only: No dishwasher. Dry immediately.

Magnetic strip or knife block: No loose drawer storage.

Wood or plastic cutting boards: No glass, ceramic, or marble.

FAQ

Is a santoku or chef's knife better for beginners? Either works for beginners. The santoku's shorter length and lighter weight are slightly more manageable for smaller hands or less experienced cooks. The chef's knife is more versatile for tasks that require length. Buy whichever fits your hand better when you hold it.

Can I use a santoku for meat? Yes, within limits. Slicing boneless chicken, beef, and pork works well. The santoku is not designed for breaking down whole birds or cutting through bone. Use a chef's knife or boning knife for those tasks.

Why does my santoku have those oval hollows on the blade? Those are a granton edge, designed to reduce food sticking during slicing. They create small air pockets that break the suction between the blade and thin food slices like cucumber rounds or fish.

Does a santoku need a different sharpening technique than a chef's knife? The angle may be different (15 to 17 degrees vs. 20 degrees), but the technique on a whetstone is the same. If your santoku is Japanese-made, use the 15-degree angle. If it's a Wusthof or other German-style santoku, use 20 degrees.

The Bottom Line

A santoku is the right primary knife if you prefer a push-cut technique, work mostly with vegetables and fish, have smaller hands, or simply find 6 to 7 inches more comfortable than 8. It's not a replacement for everything a chef's knife does, but for daily vegetable prep and precision slicing work, it's an excellent tool. Start with the MAC Superior or Tojiro DP if you want a quality Japanese santoku, or the Wusthof Classic if you want German durability in santoku form.
