The Gyuto Knife: Master the Japanese Chef's Knife

A gyuto knife is the Japanese version of the Western chef's knife. It's an all-purpose blade for slicing, dicing, and chopping. The name translates to "cow sword" in Japanese, from when these knives were first used for cutting beef, though now they handle everything from vegetables to fish.

The gyuto has a thinner blade, harder steel, and sharper edge angle than Western chef knives. It cuts with less resistance, holds its edge longer, and gives you better control for delicate work.

What makes a gyuto knife different from a Western chef's knife?

The differences go beyond looks. Gyutos are built differently, and it changes how they work.

Blade thickness and weight

Gyuto blades are 1.5-2mm thick at the spine. Western chef's knives are 2.5-3mm. You feel this when you're slicing through a ripe tomato or cutting paper-thin ginger - there's less resistance.

The thinner blade also means less weight. A 210mm Western chef's knife weighs 280-320g. A gyuto the same length weighs 200-260g. After an hour of prep work, you'll notice.

Edge angle and sharpness

Western knives are sharpened at 20-22 degrees per side (40-44 degrees total). Gyutos are 12-15 degrees per side (24-30 degrees total). That narrower angle is sharper and glides through food instead of wedging it apart.

Both styles are double bevel, sharpened on both sides. But the gyuto's acute angle needs harder steel to keep the edge from rolling or chipping.

Steel hardness

Japanese knives use steel rated 58-62 HRC on the Rockwell scale. High-end models reach 63-65 HRC. Western chef's knives are 54-58 HRC.

Harder steel holds an edge longer. It also supports that thinner edge angle without dulling right away. The tradeoff? Harder steel is more brittle. You need to be more careful and use proper cutting boards.

What is a gyuto knife best for?

The gyuto handles most kitchen cutting tasks. It works best with push-pull slicing motions rather than the rocking cuts you use with Western knives.

Best uses:

• Slicing boneless meat, fish, and poultry
• Chopping vegetables and herbs
• Mincing garlic, ginger, and aromatics
• Cutting fruit
• General meal prep

Not suitable for:

• Cutting through bones
• Prying or twisting motions
• Frozen foods
• Heavy chopping of hard vegetables like squash

The thin blade and hard steel that make a gyuto precise also make it fragile under lateral stress. Keep your cuts clean and use a heavier knife or cleaver for the rough stuff.

Gyuto knife sizes: how to choose

Gyutos come in 180mm to 300mm blade lengths. Most home cooks prefer 210-240mm. Your ideal size depends on your kitchen space, what you cook, and what feels comfortable.

180mm (7 inches)

A compact option for smaller kitchens or anyone who likes a lighter knife. Very maneuverable.

Pros:

• Easy to control for precise cuts
• Works well in tight spaces
• Less intimidating for beginners
• Light weight reduces fatigue

Cons:

• Limited reach for large ingredients
• More strokes needed for big jobs
• Less knuckle clearance

210mm (8.25 inches)

The most popular size, and for good reason. A 210mm gyuto balances versatility and control better than any other length. Most manufacturers optimize their designs around this size.

Pros:

• Handles 90% of kitchen tasks
• Good balance of control and cutting surface
• Enough knuckle clearance for most people
• Easy to store and maintain

Cons:

• Can feel short for very large ingredients
• Taller cooks sometimes want more length

Our gyuto knife is 205mm, right in this sweet spot.

240mm (9.5 inches)

Professional chefs and home cooks who prep large quantities tend to prefer this length. More cutting surface, better knuckle clearance.

Pros:

• Great for large ingredients and big cutting boards
• Fewer strokes for the same amount of prep
• Feels professional
• Better clearance for larger hands

Cons:

• Unwieldy in smaller kitchens
• Takes up more storage space
• Heavier than shorter options
• Harder to control for detail work

270mm+ (10.5+ inches)

Professional kitchen territory. Unless you're breaking down whole fish or prepping for a restaurant, skip this size.

Understanding gyuto knife construction

How a gyuto is made affects how it performs, how long it lasts, and what you pay. Two main methods: single-steel forging and laminated (san-mai) construction.

Single-steel construction

The entire blade is one type of steel. Straightforward and traditional. You can thin and sharpen these aggressively over their lifetime.

High-carbon steel versions hold an edge well and sharpen easily, but you need to stay on top of maintenance to prevent rust. Stainless steel versions are easier to care for but don't perform quite as well.

San-mai (three-layer) construction

A hard carbon steel core sandwiched between softer stainless steel layers. You get the cutting performance of carbon steel with the corrosion resistance of stainless on the outside.

Easier to maintain than pure carbon steel, still cuts excellently. Yuzu knives use this construction - AUS-10 high carbon steel core with 430 stainless steel outer layers.

Common steel types

AUS-10: Japanese high-carbon steel rated 58-60 HRC. Balances hardness, edge retention, and sharpening ease. Stain-resistant but not fully stainless. This is what's in our gyuto core.

VG-10: Popular stainless steel at 59-61 HRC. Holds an edge and resists corrosion well. Some people find it harder to sharpen than AUS-10.

Blue Paper Steel (Aogami): Traditional carbon steel, 63-65 HRC. Holds an edge exceptionally well but needs careful maintenance to avoid rust.

White Paper Steel (Shirogami): Pure carbon steel. Easier to sharpen than blue paper, same maintenance requirements.

How to care for your gyuto knife

Japanese knives need more attention than Western knives because of the harder steel and thinner blades.

Daily care

Hand wash right after use with mild soap and warm water. Don't put it in the dishwasher. The harsh detergents, heat, and rattling around will damage the edge and can crack the handle.

Dry the blade completely before you put it away. Even stainless steel can develop rust spots if you leave it wet. Carbon steel will rust fast.

Store it in a knife block, on a magnetic strip, or in a sheath. Tossing it in a drawer will dull the edge and is asking for an accident.

Cutting surfaces

Use wood or soft plastic cutting boards. Glass, marble, ceramic, and bamboo are too hard. They'll dull your edge quickly and can chip the blade on harder gyutos.

Sharpening

Sharpen on whetstones, not pull-through or electric sharpeners. Those can damage the thin edge. A dual-sided whetstone with 1000 and 3000-6000 grit covers most home needs.

Keep the original edge angle when you sharpen - usually 15 degrees per side for Japanese knives. If you're new to whetstones, use an angle guide until you get the feel for it.

How often depends on how much you use it. Most home cooks sharpen every 2-4 weeks. Use a honing rod between sharpenings to straighten the edge.

Choosing your first gyuto knife

What to consider beyond price:

Blade length: Start with 210mm unless you have a specific reason to go different. Most versatile size.

Handle style: Traditional Japanese wa-handles (wood, octagonal) or Western yo-handles (contoured plastic or wood). Try both if you can - it's personal.

Steel type: For your first gyuto, get stainless or semi-stainless like AUS-10 or VG-10. More forgiving while you're learning proper care.

Weight and balance: Should feel balanced when you pinch grip it (thumb and forefinger on the blade just in front of the handle). Some people like blade-heavy for chopping, others want neutral balance for control.

Budget: Good gyutos start around £80-120. Mid-range (£120-250) works well for most people. Above £250, you're paying for premium materials, hand-forging, or artisan work.

Conclusion

The gyuto is Japanese knife-making applied to an all-purpose kitchen blade. The thin profile, hard steel, and acute edge angle deliver performance Western knives can't match, especially for vegetables, fish, and boneless meats.

A 210mm gyuto is probably the most useful knife you'll own. Handles everything from breaking down a chicken to fine herb work. With proper care, it'll last decades.
