Petty knives are great for all the little things: Chopping shallots and garlic, mincing herbs and butchering small proteins. They function perfectly as a line knife for our professional chefs out there as they're nimble, don't take up much space but can still accomplish a wide variety of tasks. This also makes them a great option for home cooks looking for something capable they can leave out on the counter all day.

The petty knife is the Japanese equivalent of a utility knife. They typically range in size from 90 mm (3.5 inches) to 150 mm (6 inches) and have a slender, easy-to-control, short blade. They are a perfect accompaniment to a Gyuto, Santoku, or Bunka, as they facilitate smaller tasks. Shorter versions are great for in-hand use. Longer versions are great for fine chopping and managing small ingredients on a cutting board. They also handle butchery tasks with ease.
An excellent choice for everyday culinary work, 440 C is a time-tested classic known for its balance of performance and practicality. It features a stable 58–60 HRC hardness that delivers steady edge life while remaining remarkably easy to sharpen. Thanks to its high chromium content, the blade offers excellent corrosion resistance against moisture and food acids with minimal maintenance. While it lacks the extreme edge retention of premium powder metallurgy steels like R2 or SPG STRIX, this 440C construction serves as a highly practical, durable, and budget-friendly workhorse for daily kitchen use.
LOW MAINTENANCE
Stainless steel Japanese knives are made in a process called “Sanmai” or “Forge welding” where two softer layers of stainless steel are laminated around a harder core layer of stainless steel. All three of these layers are rust resistant and therefore are not susceptible to rust or discoloration. The softer outer layers of steel are used to make the knife more durable and flexible while the harder core layer is used to provide better edge retention to the blade.
Tsunehisa seeks to make great knives at affordable prices. Their knives are machine forged, as opposed to being hand forged; however, many of the knife making processes are still done by hand. This combination of machine and human touch ensures the knives have a fantastic fit and finish, high performance capabilities, and extreme consistency. These knives are fantastic for the home cook or the professional looking for great performance, easy maintenance, and beautiful aesthetics.
