Nakiri and usuba knives are both traditional Japanese vegetable knives, but they differ significantly in design and intended use. While nakiri knives are double-bevelled and tailored for straightforward chopping, usuba knives are typically single-bevelled, designed for precision cutting and professional use.

Understanding these differences is key to choosing the right knife for your kitchen. The blade angle, edge type, and blade shape affect how each knife performs with vegetables, impacting cutting technique, ease of sharpening, and maintenance.
Where each one wins
Nakiri knives excel at quick, efficient vegetable chopping for home cooks who want a straightforward knife that handles a variety of produce with minimal technique. Their symmetrical edges reduce the learning curve and make maintenance simpler. They are also more forgiving on chopping boards that are softer or uneven.
Usuba knives are best suited for professional chefs or serious enthusiasts who prioritise precision cutting. Their single bevel edges allow for wafer-thin slices, fine juliennes, and decorative cuts that nakiri knives cannot replicate as cleanly. However, this precision comes at the cost of increased sharpening difficulty and a need for practiced handling.
For most home kitchens, a nakiri knife is the practical choice. The usuba knife is worth investing in if you regularly prepare dishes requiring elaborate vegetable presentation or if you have experience with single bevel knives.
Delving deeper into the mechanics, the nakiri’s double bevel edge is typically sharpened to around 12–15° per side, creating a balanced edge that is robust enough for repeated chopping motions without chipping easily. This geometry supports straight up-and-down cuts, making it ideal for dicing and slicing vegetables quickly. The blade’s thinner profile, often around 2 mm at the spine tapering to a fine edge, reduces resistance when cutting, allowing for smooth, effortless chopping.
In contrast, the usuba’s single bevel edge is sharpened to a more acute angle, approximately 9–12°, on one side only, while the opposite side is flat or concave. This asymmetry enables the blade to slice vegetables with exceptional precision, producing thin, clean cuts with minimal crushing or tearing. The blade is generally thicker and heavier than the nakiri, around 3 mm at the spine, providing stability during delicate slicing tasks such as katsuramuki (rotary peeling) or usuzukuri (thin slicing). This thickness also helps maintain blade integrity despite the acute edge angle.
The cutting techniques differ significantly. Nakiri knives favor a push-cutting style, where the blade moves straight down and forward, leveraging the flat edge to chop through vegetables efficiently. This style minimizes wrist movement and is accessible for home cooks. Usuba knives, however, require more nuanced wrist control and slicing motions to utilize the single bevel edge effectively. The blade’s bevel side faces the food, guiding thin slices away from the blade and allowing for precise control over thickness.
Sharpening and maintenance reflect these differences. Nakiri knives, with their symmetrical edges, can be sharpened on standard whetstones using simple techniques. They tolerate occasional lapses in maintenance and are less prone to chipping, making them user-friendly. Usuba knives demand specialized sharpening methods, often requiring the use of a nagura stone to maintain the concave side and careful angle control on the bevel side. Improper sharpening can quickly ruin the delicate edge, and the single bevel design makes them more susceptible to chipping if mishandled.
The user experience is also shaped by handedness. Nakiri knives are generally ambidextrous, suitable for both right- and left-handed users due to their double bevel. Usuba knives are typically ground for right-handed use, with the bevel on the right side, making left-handed versions rare and custom-made. This orientation affects cutting precision and comfort, so left-handed users should consider this carefully.
In terms of consequences, choosing the wrong knife for your needs can impact cooking efficiency and food presentation. Using a nakiri for ultra-thin slicing may result in uneven cuts and bruised vegetables, while using an usuba without proper skill can lead to chipped edges and frustration. Investing time in mastering the usuba can yield impressive garnishing results, but for everyday cooking, the nakiri’s versatility and ease of use often provide better value.
| Attribute | Nakiri knife | Usuba knife |
|---|---|---|
| Edge type | Double bevel, sharpened on both sides (approx. 12–15° per side) | Single bevel, sharpened on one side (approx. 9–12°), flat or concave opposite side |
| Blade shape | Rectangular with squared tip, thinner blade profile | Rectangular with squared tip, generally thicker blade profile |
| Cutting style | Push cut and chopping with vertical motions | Precise slicing and shaving with controlled strokes |
| Ease of sharpening | Relatively easier due to symmetrical edge | More challenging; requires skill and special whetstones |
| User handedness | Ambidextrous (usable by right and left-handed) | Typically right-handed only due to bevel orientation |
| Maintenance | Lower maintenance; less prone to chipping | Requires careful maintenance to avoid chipping single bevel edge |
From my kitchen
Once, while preparing a vegetable platter for a dinner party, I switched between my nakiri and usuba knives to compare their effects. The nakiri sliced through carrots and cucumbers quickly but left edges that were slightly crushed on softer vegetables like tomatoes. The usuba, with its single bevel, cut thin slices of daikon with razor-sharp precision, producing clean, crisp edges that held shape in a salad.
However, I found myself spending extra time sharpening the usuba after extended use, and it required more careful handling to avoid chipping the edge. For everyday vegetable prep, the nakiri saved time and effort, but when it came to fine garnishing, the usuba was unmatched.

When neither nakiri nor usuba is the right choice
If your vegetable prep involves heavy-duty tasks like cutting through thick roots or tougher produce, or if you also require a knife that handles meat or fish, neither nakiri nor usuba knives are ideal. Their thin blades and specialised edges can chip or dull quickly under such stress.
In such cases, a santoku or a general-purpose chef’s knife with a thicker blade and more robust edge geometry would be a better investment. These knives can handle a wider variety of tasks without frequent sharpening or risk of damage.
Also, if maintenance and sharpening skill are concerns, a double bevel santoku or chef’s knife offers easier upkeep than a single bevel usuba.
Frequently Asked Questions
Can left-handed users use an usuba knife?
Most usuba knives are single bevel and ground specifically for right-handed use, meaning the bevel is on the right side of the blade. Left-handed versions exist but are rare and often more expensive. Using a right-handed usuba knife left-handed will result in awkward cuts and increased risk of injury. If you are left-handed, a double bevel nakiri knife is usually a better choice.
How often should I sharpen a nakiri or usuba knife?
Frequency depends on use and blade quality. A nakiri knife with a double bevel edge may only need honing every few uses and sharpening every few months. An usuba knife’s single bevel edge dulls faster with delicate use and requires more frequent honing, with sharpening needed roughly every few weeks or after heavy use. Proper sharpening stones and technique are essential, especially for usuba knives.
Can I use a nakiri knife for meat?
Nakiri knives are optimised for vegetables, with a thin, flat blade designed to cut cleanly through produce without twisting. Using them on meat can damage the edge and cause chipping because the blade is not designed for cutting through sinew or bone. For meat, a chef’s knife or specialized boning knife is better suited.
