The Nakiri Knife: Your Complete Guide to the Japanese Vegetable Knife

A nakiri knife is a Japanese vegetable knife with a flat, rectangular blade. Unlike curved chef's knives that rock through ingredients, the nakiri's straight edge cuts cleanly from heel to tip in one downward motion. No partial cuts, no accordion vegetables still connected at the bottom.

The name comes from the Japanese "nakiri bōchō," meaning "knife for cutting greens." It's standard equipment in Japanese home kitchens and increasingly common with Western cooks who do a lot of vegetable prep.

What makes a nakiri different from other knives?

The nakiri looks nothing like a Western chef's knife. The blade is rectangular, almost cleaver-like, but thin and light.

The edge runs perfectly straight. No curve, no belly. When you chop, the entire blade hits the cutting board at once. This matters because curved blades often leave vegetables partially connected unless you complete a full rocking motion.

Nakiri blades run 165-180mm long and stand tall enough to clear your knuckles. The blade itself is thin, often under 2mm, which means less resistance when you're cutting through dense vegetables like butternut squash or cabbage.

Unlike the single-bevel usuba that professional Japanese chefs use, the nakiri has a symmetrical edge sharpened on both sides. Easier to control, works for left or right-handed users, and more forgiving if your technique isn't perfect.

The squared-off tip isn't meant for piercing or detail work. It just maximises blade length for chopping. Some people find it safer for rapid cutting since there's no sharp point to worry about.

What is a nakiri knife used for?

Vegetables. That's really it. The nakiri is the definitive Japanese vegetable knife because it does one thing well rather than many things adequately.

Among Japanese chef knives, the nakiri stands apart as a pure specialist. Where a gyuto tries to cover everything, this Japanese vegetable knife is purpose-built for plant-based prep and nothing else.

Rapid chopping

Onions, carrots, celery, peppers. The nakiri moves through aromatics quickly once you get the rhythm. Straight up-and-down motion, no rocking required. It feels different from a chef's knife at first, then it clicks.

Thin, uniform slices

The thin blade and flat profile give you consistent slices for cucumber salads, courgette ribbons, or aubergine rounds. Each cut is clean from top to bottom. No tearing, no crushing. This is where the nakiri's design as a Japanese vegetable knife really shows: the flat edge and tall blade give you control that curved knives can't match on produce.

Dense vegetables

Butternut squash, sweet potatoes, celeriac. Vegetables that fight back against a curved blade respond well to the nakiri's straight-down cut. The thin blade wedges through with less force than thicker Western knives.

Herbs and leafy greens

The wide, flat blade works for chiffonade cuts on basil or shredding cabbage. You can also use it to scoop chopped ingredients and transfer them to the pan.

Can you use a nakiri knife to cut meat?

Technically, yes. You can use a nakiri knife to cut boneless chicken breasts, salmon fillets, or other soft proteins without bone. The sharp edge will get through them. But "can" and "should" are different questions.

The nakiri's flat edge and lack of belly work against you on meat. With proteins, you often want a slight rocking or drawing motion to slice cleanly through sinew and connective tissue. The nakiri doesn't allow for that. Its straight up-and-down chopping motion, perfect for vegetables, feels clumsy and imprecise on a chicken thigh.

If you're cooking meat regularly, a gyuto knife is what you want. It has the curve for rocking cuts, the tip for precision work, and enough blade weight to handle proteins properly. The nakiri stays in its lane as a vegetable specialist. And whatever you do, don't use a nakiri on bones or frozen foods—that's a fast route to a chipped edge.

How to use a nakiri knife

The nakiri requires different technique than Western chef's knives. The adjustment takes a few sessions, then becomes second nature.

The grip

Use a pinch grip. Thumb on one side of the blade just ahead of the handle, index finger on the other side. Remaining fingers wrap around the handle. This gives you control over the blade itself, not just the handle.

The cut

Forget rocking. The nakiri works with a straight up-and-down chop or a push-cut where you guide the blade forward and down through the ingredient. The entire edge contacts the board at once.

The guide hand

Curl your fingertips under your knuckles to form a claw shape. Rest your knuckles against the flat of the blade as a guide. This protects your fingers and helps maintain consistent slice thickness.

Speed comes later

Start slowly. The rhythm feels unfamiliar at first. Once the motion becomes automatic, you'll move through vegetables faster than you did with a chef's knife.

Nakiri vs usuba: what's the difference?

Both are Japanese vegetable knives. They look similar. But they're made for different users.

The usuba is a single-bevel knife for professional Japanese chefs doing decorative cuts and paper-thin slices. It takes real skill to use well. The asymmetrical edge wants to steer to one side, and the thin blade chips easily if you're careless.

The nakiri is the home cook's version. Double-bevel sharpening makes it forgiving. You won't match an usuba's decorative precision, but for everyday vegetable prep, the nakiri is more practical and easier to maintain.

Nakiri vs gyuto: do you need both?

A gyuto handles meat, fish, and vegetables. It's a generalist. A nakiri only does vegetables. It's a specialist.

If you're buying your first quality Japanese knife, the gyuto probably makes more sense. It covers more ground. But if vegetables make up a big part of your cooking, adding a nakiri pays off. Meal prep, plant-based dishes, lots of stir-fries and salads.

The straight edge and tall blade make vegetable work faster and more precise. People often end up reaching for the nakiri more than they expected. If you're building out a full set of Japanese chef knives, the nakiri and gyuto complement each other well. Add a petty knife for detail work and you've got most tasks covered.

What to look for in a nakiri

Quality varies. Here's what actually matters.

Steel type

The blade steel affects sharpness, edge retention, and maintenance.

• High-carbon stainless (like AUS-10) balances sharpness, durability, and corrosion resistance. Best choice for most home cooks.
• Carbon steel gets sharper and resharpens easily, but needs more care to prevent rust and discolouration.
• Standard stainless is low-maintenance but won't hold an edge as long.

Blade thickness

Thinner cuts with less resistance. Look for under 2mm at the spine. Thicker blades feel clunky on vegetables and need more force.

Handle style

Traditional Japanese "wa" handles are lightweight and comfortable for long prep sessions. Western handles offer a different grip. Neither is objectively better. If you already own Japanese knives, matching handle styles keeps your grip consistent across your collection.

Balance

Good nakiris feel balanced, not blade-heavy or handle-heavy. This matters when you're doing the same up-down motion dozens of times during prep.

Caring for your nakiri

Japanese knives reward good care. Neglect them and they rust, chip, or go dull. Look after them and they last years.

Cleaning

Hand wash right after use with warm water and mild soap. Dry completely before storing. Never put it in the dishwasher. The jostling damages the edge, and prolonged moisture causes corrosion.

Storage

Use a knife block, magnetic strip, or protective saya (wooden sheath). Don't toss it in a drawer where the edge knocks against other utensils.

How to sharpen a nakiri knife

A whetstone is the best way to maintain a Japanese knife. Use medium grit (around 1000) for regular sharpening and finer grit (3000+) for polishing. Keep the original edge angle, typically 15 degrees per side.

The nakiri's flat edge actually makes it one of the easier Japanese knives to sharpen. There's no curve to follow, so you maintain a consistent angle as you draw the full length of the blade across the stone. Hold the blade flat against the whetstone, raise the spine to your target angle, and use smooth, even strokes. Work one side, then the other, alternating until you've removed the burr.

Frequency depends on use. Daily cooking means sharpening every two to three months. Light use can go longer.

What to avoid

• Glass or ceramic cutting boards (use wood or plastic)
• Twisting the blade while cutting
• Bones, frozen food, or hard seeds
• Leaving the knife wet or food-stained

The Yuzu nakiri

Our nakiri knife is AUS-10 high-carbon steel. Hard enough to hold a sharp edge, tough enough to resist chipping, and more corrosion-resistant than pure carbon steel.

The san-mai construction sandwiches the AUS-10 core between layers of softer stainless steel for durability while keeping the cutting edge precise. The kurouchi (blacksmith's finish) helps food release from the blade and protects against rust. It also looks good, though that's secondary.

The wa handle is ebony and sandalwood. Balanced, comfortable through long prep sessions. At £95, it's the same steel and construction as knives costing twice as much from boutique brands.

The nakiri starter kit includes a whetstone and saya for £129 if you're starting from scratch.

Is a nakiri worth it?

Depends how much vegetable prep you do.

If vegetables are a regular part of your cooking, probably yes. The nakiri does one job and does it better than any general-purpose knife. Faster chopping, cleaner slices, less effort on dense produce.

It won't replace your chef's knife for everything else. But for plant-forward cooking, meal prep, or anyone who simply eats a lot of vegetables, it's a useful addition.
