Sushi and Sashimi Knives
What Makes it a Sushi Knife?
Sushi and Sashimi knives are extremely sharp, hand-crafted for a specific task, and require very specific instructions to handle and maintain.
There are many steps to making a sushi roll: cutting vegetables, cutting fish, and then cutting the roll itself. A sushi knife is multifaceted for cutting during all three, but a sashimi knife is made specifically for cutting fish.
Most sushi knives are made of high-carbon steel (not stainless steel). This means that the steel rusts easily, but is capable of attaining a much sharper edge.
One unique trait of sushi and sashimi knives is their single beveled edge. These knives are sharpened so that only one side holds the cutting edge and the other side remains flat. The flat edge is there so that food doesn’t stick to the knife.
It is rumored that most sushi knives are right-handed because it is better to cut fish with, whereas left-handed knives are better for cutting shellfish. Left-handed knives are usually custom-made and more expensive.
Another unique quality of the knives is the handle. Traditionally, the handle was shaped with a “D” cross-section. This was to make using the knife for long periods of time more comfortable. The handles are made with various types of wood and usually a bone cap towards the top.
The last unique trait of sushi and sashimi knives (which can also be seen in Japanese Katana) is the Tang. The tang refers to the metal portion of the handle that runs down the length. There are full tang knives and half tang knives. Full tang runs the entire length of the handle whereas half tang does not.

While there are a few more types of knives used in the sushi industry, they are extremely rare and absolutely accessories to the essential knives. The above listed are considered the “essential” knives for sushi.

Buying a Sushi Knife
In this section, I will go over the Do’s and Don’ts of buying knives. There are plenty of websites out there that will tell you that they sell “high quality, cheap knives.” But I assure you, the terms “high quality” and “cheap” don’t belong in the same sentence when it comes to sushi knives. You definitely get what you pay for.
There are two main groups of how a sushi knife is crafted:
- Honyaki (true forged)- made from a single, high-grade steel
- Kasumi (mist)- made from two types of high-grade metal (usually a hard, iron center and softer high carbon steel)
If money isn't an issue, buy a Honyaki.
A Honyaki knife is typically a higher-quality knife. Made by a single piece of steel and using a more traditional crafting/cooling process, a honyaki will have a higher carbon content without sacrificing its durability. Though, you should be careful of retailers that claim their knives are honyaki. Do a little research on the makers of the blades and always watch the price point. I would say that a good starting price for a true honyaki is about $500USD.
What about the Tang?
Previously I thought that a full tang was the only way to go. However, unless you are planning to go into combat or use your knife to pry open your car door (please don’t), you don’t need a “full tang.” In fact, there are some chefs that argue that a full tang knife has higher sanitation risks! There are several styles of knives that have a full tang with two pieces of the handle riveted onto it; these are typically seen in European knives.
Traditional Japanese knives use a partial tang or a “rat tail.” This means that the metal from the blade is tapered down and surrounded by the handle. The main reasoning for this is to secure the blade to the handle and add more balance to the weight of the blade.
If you order a knife and you can see a gap between where the neck ends and the collar begins (this is the bone or horn cap on the handle), send it back. The blade needs to be completely seated within the handle when you purchase your knife. In my experience, seeing that gap leads to the blade becoming completely unseated over time.
History of Sushi Knives
The techniques of handcrafting sushi knives date back to the 14th century-with many of the techniques (from swordsmiths) going back as far as 1000 years ago. During the modernization of Japan (19th century), carrying Samurai swords became illegal. As such, the majority of sword craftsmen turned their business towards crafting sushi knife cutlery.
As with every art form in Japan, there are hundreds of years of accumulated knowledge and experience that are passed down from master to apprentice. Specific rules and procedures put into place and secrets of the trade passed on by personal exposure- Creating sushi knives is no exception.
In Japan, there is one region that is world-renowned for its metalwork- Sakai City. Sakai has been known for their metalwork since 500 A.D. after one of Japan’s emperors died and decreed that a temple be built in his name.
After the temple was complete (many years before his death), many of the blacksmiths settled around Sakai permanently. Having all of the best blacksmiths of Japan living in one place, it’s no wonder that Sakai became famous for their work.
Starting with swords, then rifles after the Portuguese introduced them, and then eventually sushi knives- Sakai, to this day, is known for their high-quality metalwork.
Sushi Knife FAQ
Honestly, I went through two years of working at different sushi bars before investing in one of my own. Owning your own knife isn’t necessary, but it is convenient.
This is entirely up to what you plan on doing with it. As a general rule of thumb, a Yanagiba will be the only knife that you will need (other than the knives you already own). However, as you start to make sushi more often you might want to consider getting other sushi and sashimi knives, such as an Usuba or Deba.
Don’t buy stainless steel sushi knives! No questions asked. Stainless steel knives used for sushi are not as efficient, produce more mess than they are worth, and are not traditional. Don’t buy them.
Sashimi is traditionally cut using a yanagiba (also referred to as a yanagi or yanagiba-bocho)
Most sushi chefs in the United States start with a yangiba to slice sashimi and rolls. Chefs will then expand their knife set with a deba and usuba. If other knives are needed, they will usually come after the core 3 knives are purchased.
Most sashimi knives will be between 9 – 12 inches in blade length.
The most common type of sushi knife is called a yangiba.
