So, you’ve decided to dive into the rabbit hole of Japanese sushi knives!

There are quite a few different options, including as you may have guessed, the Shobu knife.  While many knives can be used to cut fillets of fish and create beautiful sashimi, there are a few different knife styles that are designed specifically for precise slicing of seafood.  The Shobu being the focus of this article, however the Yanagiba and the Takohiki are other knives that can be used for similarly spectacular results.

Originating in Western Japan, sushi knives such as the Shobu and the Yanagiba have a long heritage. Both names translate to leaves, with Shobu being Iris Leaf and Yanagiba translating to Willow Leaf, both of which imbue the flexible and effective nature of this slicing blade. Located primarily in Osaka and Kyoto, the Shobu knives would quickly spread throughout Japan as one of the more desired sushi knives on the market.

Introducing the Shobu Knife

The Shobu knife is an incredibly important tool in kitchens worldwide. The sushi knife is ideal due to its single bevel design, generous length, coupled with a slim shape and light weight.  Traditionally made out of carbon steel, Shobu knives can slice seafood with ease, leaving a pristine cut that is pleasing to the eye as well as the taste buds.  Due to these characteristics the Shobu is the perfect sushi knife for working with all types of fish, octopus, and other seafood.

Originating from the ancient art of Japanese sword making, individuals can incorporate similarly impressive kitchen tools to their home by shopping for hand forged Shobu knives made by talented craftsmen. First originated in Western Japan in Osaka and Kyoto, the sushi knife would become a household item because of the work of master blacksmiths like Doi-san at Sakai Takayuki. Sakai Takayuki has followed a  600-year history of crafting artisan Shobu Knives for clients around the world.

Perfect Kitchen Companion: The Shobu Knife

The Shobu knife has been admired for its ease of use with boneless fish, but there are a variety of other advantages that the blade can provide.  Check out these Shobu knife characteristics:

  • Single Bevel — The Shobu knife features a single angle, with one side of the blade being flat. The single-bevel design allows for quick and precise cuts that retain control for smaller slices. By minimizing stroke-and-pressure, the Shobu blade can better cut fish without damaging the surface of the meat. For more information we have a great article on the difference between single bevel vs double bevel knives.
  • Left-handed and Right-handed blades – When shopping single bevel kitchen knives, it should be noted that you need to buy the correct version for your dominant hand. Left-handed versions are typically available but may need to be specially ordered.
  • Great Sashimi Knife — Valued by locals as a fantastic sashimi knife, the Shobu blade, when sharpened, features a single-motion cut that can create precise cuts and beautiful sashimi, pleasing to the eyes and the tastebuds. Single-motion slicing makes the Shobu Knife a necessity for sushi and sashimi preparation.
  • Easy to Handle — The Shobu and Takohiki knives are perfect knives for sashimi due to the incredibly ease of use and dexterity. Lightweight with a single bevel edge, the ease with which it slices and can be sharpened make the Shobu ideal for sashimi.

Of the different Japanese kitchen knives out there, the Shobu knife is by far one of the longer knives available.  While it is long, it is also slender, allowing for minimal surface area, minimizing friction while slicing the seafood.  The length allows for minimal back and forth when slicing a piece of sashimi, optimally only one motion.

Steel Types of the Shobu Knife

Like many Japanese kitchen knives, the Shobu knife is created in a variety of steel types.  High-end traditional Japanese knives are typically made out of Shirogami, also known as White Steel.  However, the Shobu, as with other sushi knives, can also be found in Stainless Steel versions.  Both have their benefits.  Check out our Material Types page for more info.  Ultimately it is entirely a personal choice and cooking style.  Many traditional Japanese chefs prefer the Shirogami due to the razor-sharp edge that is achievable.  With the razor-sharp edge, the blade slices through the fish with ease which creates less damage to the meat.
