Japanese Sashimi Knife: The Complete Guide to Yanagiba and Its Relatives

If you want to cut sashimi properly, you need the right knife. A chef's knife can slice fish, but it won't give you the clean, silken cuts that define professional sashimi presentation. That takes a specialized blade, and the Japanese sashimi knife has been refined over centuries specifically for this purpose.

This guide covers everything you need to know about Japanese sashimi knives: the different types, how they work, what steel options are available, and how to choose the right one for your skill level and budget.

What Is a Sashimi Knife?

A sashimi knife is a long, thin, single-bevel Japanese knife designed for slicing raw fish into clean, precise cuts. The most common style is the yanagiba (also written yanagi-ba), a blade that's typically 270-330mm long with a pointed tip and single-bevel edge ground only on one side.

The single bevel design is the defining technical feature. Because the blade is ground flat on one side and angled on the other, the cutting face lies flat against the fish, allowing for a pure pulling cut that separates the cells of the fish rather than crushing them. The result is a cleaner cut surface, better texture, and more visually appealing presentation.

This is meaningfully different from cutting with a double-bevel blade, where both faces meet at the cutting edge at equal angles. That design works fine for most cutting tasks but doesn't achieve the same result on delicate raw fish.

The Main Types of Japanese Sashimi Knives

Yanagiba

The yanagiba is the standard sashimi knife used in most Japanese restaurants and home kitchens. The name means "willow leaf" in reference to the blade shape: long, narrow, with a graceful taper to a pointed tip. Blade lengths run from 210mm (smaller home kitchen options) to 360mm (professional sushi chef length). Most home cooks are well-served by a 270mm blade.

The single-bevel edge is ground to the right side for right-handed use. Left-handed versions exist but are special orders from most manufacturers. This handedness distinction is important when purchasing.

Takohiki

The takohiki is a sashimi knife specifically associated with Tokyo-style sushi traditions. Where the yanagiba has a pointed tip, the takohiki has a squared-off tip. Traditionally used for cutting octopus (tako means octopus in Japanese), it's used today for sashimi generally. Less common than the yanagiba, but preferred by some sushi chefs.

Fuguhiki

The fuguhiki is a flexible, very thin yanagiba variant designed for slicing fugu (puffer fish) into translucent slices. The blade is thinner and more flexible than a standard yanagiba. Unless you're specifically cutting fugu or paper-thin slices of other delicate fish, this is not a tool most cooks need.

Kiritsuke Yanagiba

The kiritsuke is a hybrid between the yanagiba and the usuba (a vegetable knife). It has a pointed, angular tip rather than the curved tip of the yanagiba. Traditionally, in Japan, only the head chef of a kitchen used a kiritsuke, as it was a prestige tool. Today it's available to anyone. The angled tip makes precise detail cuts easier.

Understanding the Single-Bevel Edge

The single-bevel edge requires a different approach than Western knife sharpening. The flat (ura) side of the blade is kept completely flat during sharpening, never creating a secondary bevel. Only the angled (shinogi) side is sharpened. This preserves the geometry that makes the knife work correctly.

Getting this right matters. Putting even a tiny secondary bevel on the ura side compromises the knife's performance. If you're new to single-bevel sharpening, practicing on an inexpensive knife before working on a quality yanagiba is wise.

The factory edge on most quality yanagiba is exceptionally sharp, often sharper than anything you can achieve at home without significant skill. The first sharpening session is mostly about maintenance, not improvement.

Steel Types for Sashimi Knives

White Paper Steel (Shirogami)

White steel, called shirogami in Japanese, is a simple high-carbon steel with high purity and very few alloying elements. It takes the sharpest possible edge of any kitchen knife steel, is easy to sharpen, and has excellent feedback while sharpening. The downsides: it rusts quickly and requires immediate drying after use. For the sharpness and edge quality it offers, most serious sashimi cutters consider this tradeoff worthwhile.

Blue Paper Steel (Aogami)

Blue steel (aogami) adds tungsten and chromium to the white steel base, increasing edge retention while maintaining much of the sharpness potential. It's slightly harder to sharpen than white steel but holds its edge noticeably longer. A good choice for cooks who want excellent performance with somewhat less maintenance than white steel.

Stainless Steel (e.g., AUS-10, VG-10, Ginsan)

Stainless sashimi knives sacrifice some peak sharpness and edge quality compared to carbon steel options, but they're much more forgiving for daily use. They won't rust with normal care, and they don't require the same attentiveness that carbon steel demands. Ginsan (Silver Paper Steel) is a favorite in this category because it performs closer to carbon steel than most stainless options while still resisting rust effectively.

For home cooks who won't be maintaining their knife obsessively, a stainless or semi-stainless option is often the practical choice.

Handle Styles

Traditional Japanese sashimi knives use a wa-style handle: an octagonal or round wooden handle with a blade tang inserted into it. The handle is much lighter than Western knife handles, shifting the balance point toward the blade. This feels very different from a Western pinch grip.

Most wa handles are made from magnolia (ho wood), which is plain and replaceable. Higher-end knives come with handles made from rosewood, ebony, or stabilized woods.

Some modern yanagiba are made with Western-style handles for buyers more comfortable with conventional grip. These are fine options for home use, though traditional Japanese knife enthusiasts generally prefer the wa handle for the balance it creates.

Choosing the Right Length

For home cooks cutting fish for 2-4 people, a 270mm blade works well. It's long enough to slice through most fish in a single pull without repositioning, but not so long that it's awkward in a home kitchen.

Professional sushi chefs often use 300mm or longer. This allows for a complete pull cut across a whole salmon or tuna loin without lifting the blade. At home, you're rarely working with pieces that large.

Shorter options (210-240mm) exist for cooks with limited counter space or those just getting started with Japanese knives.

Technique for Using a Sashimi Knife

The fundamental technique is the single pull cut. Position the knife at the back of the blade near the heel, hold the fish steady with your other hand, and draw the blade toward you through the fish in one smooth, continuous motion. The idea is to use the full length of the blade in each cut.

Do not push the blade forward into the fish the way you might with a chef's knife. The single-bevel edge is designed for the pulling motion, and applying it correctly is what produces the clean result.

Cutting angle affects presentation. Slices cut at a slight angle to the grain of the fish tend to look better and have a more pleasant texture than straight perpendicular cuts.

Caring for a Sashimi Knife

Carbon steel yanagiba require immediate attention after use. Rinse in warm water, dry completely with a cloth, and store in a saya (wooden sheath) or on a covered knife rack. Never put in a dishwasher or leave sitting wet.

Stainless options are more forgiving but still benefit from the same care routine. The edge is delicate and will damage against hard surfaces.

Sharpening requires a whetstone, not a honing steel or pull-through sharpener. The single bevel requires flat-side maintenance on a 1000-grit stone, followed by edge sharpening at the correct angle. Learning this process on a video with the specific knife you own is the best approach.

What to Expect to Pay

Entry-level yanagiba in stainless steel from brands like Victorinox, Mercer, or Global start around $60-$100. These are decent quality for learning the style without a big investment.

Mid-range options from Japanese makers like Tojiro, Mac, or Masamoto come in around $100-$200. These represent good value for home cooks who want a genuine Japanese knife.

Premium hand-forged yanagiba from makers like Sakai Takayuki, Yoshihiro, or Ashi Hamono run $200-$500+. These are beautiful tools made by craftspeople with generational expertise. The performance is exceptional. They're also not necessary unless you're cutting sashimi regularly with high standards.

FAQ

Can I use a yanagiba for anything other than sashimi? Yes. A yanagiba works well for slicing any raw proteins, breaking down fillets, and cutting soft items that benefit from a long slicing cut. It's not a general-purpose knife, but it's more versatile than purely sashimi. Many cooks use a yanagiba for carving roasted meats or slicing smoked salmon.

Is a sashimi knife left or right-handed? Yes, single-bevel knives are handed. Most are made for right-handed use. Left-handed versions exist but require special ordering from most manufacturers and typically cost more.

Do I need to be an experienced knife user to use a yanagiba? The cutting technique is simple once you understand the pulling motion. The challenge is sharpening, which requires learning whetstone technique for single-bevel edges. Buying the knife is the easy part. Maintaining it properly is the skill that takes time.

What's the difference between a sashimi knife and a sushi knife? Sashimi knives like the yanagiba are for slicing raw fish and preparing ingredients. Sushi knives (yanagiba is also used for this) are used to cut assembled sushi rolls. There's overlap in usage, and most Japanese sushi chefs use a yanagiba for both tasks.

How often does a yanagiba need sharpening? With regular use, a couple times a month for home cooks. Carbon steel dulls faster than stainless, so higher-frequency maintenance is needed for carbon steel. If you learn to strop the blade lightly after each use, you can extend the time between full sharpening sessions.

Final Thoughts

A Japanese sashimi knife is a specialized tool that rewards the cooks who invest in learning to use it properly. The yanagiba is the standard starting point, and for most home cooks cutting sashimi, a 270mm stainless option from a mid-range Japanese maker is the right first purchase.
