What is a Petty (Paring/Utility) Knife?

The Petty knife, also known as the Japanese paring knife or the Japanese utility knife, is a versatile multi-purpose knife that is typically larger than a western paring knife, but smaller than a western chef’s knife or the Japanese chef’s knife, the Gyuto.

Petty knives are considered to be a smaller version of the Gyuto chef’s knife and are similarly used as an all-rounder knife to peel, slice, dice, mince, peel and trim a variety of smaller fruits, vegetables, herbs, garnishes and proteins.

Particularly loved by line cooks in professional kitchens for its compact size and versatility, the Petty knife is also highly recommended for those who:

  • have a smaller workspace
  • want a smaller knife for quick use when a full-sized Gyuto or chef’s knife would be unwieldy (to cut a lime, for example), or
  • have smaller hands and want a lighter alternative to the Gyuto

What does Petty mean?

The name of the Petty knife is said to be derived from the word ‘petit’, meaning ‘small’ or ‘little’ in French. The Petty knife is seen as a smaller version of the Gyuto, the Japanese chef’s knife. The Petty knife is also sometimes referred to as a Japanese paring knife or a Japanese utility knife.

What is a Petty knife best for?

The Petty knife is best for smaller tasks such as slicing or dicing vegetables, fruits and herbs; light butchery work; and for delicate tasks such as making precision cuts.

In particular, smaller petty knives with blades of 80-90mm are useful for off-board cutting or peeling (‘paring’) fruits and vegetables in the hand, or for fine precise work on a chopping board such as brunoise cuts and slicing herbs and garnishes.
The larger sized Petty knives with blades of 120mm to 150mm are considered to be a smaller alternative of the Gyuto chef’s knife, and are similarly used for a wide variety of tasks including slicing and dicing vegetables or fruits, trimming meat, filleting small fish, and other light butchery work. Petty knives of this size are often used by chefs and line cooks during service as the compact size takes up minimal space on the board but functions as a versatile workhorse.

Petty knife characteristics


The Petty knife is generally larger than a western paring knife but smaller than a western chef’s knife or the Japanese chef’s knife, the Gyuto. Petty knives are available in a wide variety of blade lengths ranging from 80mm to 180mm.

The most common blade lengths for a Petty knife are between 80-90mm, or 120-150mm. A 80-90mm Petty knife is ideal for peeling smaller fruits and vegetables in the hand or for fine and delicate tip work on the chopping board. A 120mm or 150mm Petty knife is best recommended as an alternative option to the Gyuto for those with small hands, or for those who have limited workspace in their kitchen.


The Petty knife shares a similar profile to the Gyuto Japanese chef’s knife and is typically tall and flat at the heel with a slight curve in the front edge of the blade, leading to its pointed tip. The relatively flat heel of the blade makes it well-suited for a variety of chopping styles such as thrust-cutting, while the slight belly towards the tip of the blade allows for easy rock-cutting. The pointed tip of the Petty knife also helps to achieve clean precision cuts.


The Petty knife typically features a double bevel blade with a razor-sharp edge, as Japanese double bevel knives are ground at a much more acute angle of 10-15 degrees than those of a western paring knife or a western chef’s knife.


Petty knife handles can be categorized into two categories: the traditional Japanese ‘Wa-Handle’, or a Western-style handle.

The most common wa-handle shapes are the D-shape, oval, or octagonal. While some prefer the ergonomic grip of a D-shaped or octagonal handle, the choice of the handle comes down to personal preference.

How are Petty knives made?

The history of the Japanese Petty knife dates back to the post-Meiji era after Japan opened its borders and began to trade with other countries. The western world started to influence everyday life in Japan including the Japanese diet, and eventually also influenced Japanese kitchens and their utensils. It is said that the Japanese adapted the Petty from the western utility knife, which originally evolved from the French office knife ‘couteau d’office’. This may be the reason that the Petty knife got its name, as the word ‘Petty’ comes from the French word ‘petite’, meaning ‘little’ or ‘small’.

To this day, traditional blacksmiths in Japan still forge Petty knives manually by hand, although many Japanese and Western knife manufacturers now offer their own versions of the Petty knife as well. The most famous cities in Japan for their knives include Sakai (in Osaka), Seki (in Gifu), and Echizen (in Fukui).

To understand how Petty knives are made and to decode the common phrases that are found in knife descriptions, it’s best to look at traditional Japanese knife forging methods and the materials used.

There are two basic categories of Japanese knives - honyaki and kasumi - which are defined by the materials and methods used in their forging.

honyaki (“true-forged”) knives are manually forged by hand following traditional Japanese blacksmithing techniques, and are created entirely out of one single material: high-carbon steel (hagane). The hagane is typically a type of White Steel (Shirogami) or Blue Steel (Aogami), and this style of knife blade is also called a mono steel blade.

The method of creating a honyaki knife is similar to how Katanas (Japanese traditional swords) were made in the past. Forging a Petty knife is a lengthy and difficult manual process that begins with a single high-carbon steel blank, and involves multiple rounds of heat treatment, steel hammering, kilning, polishing and sharpening. This is done manually in the hands of skilled blacksmiths in Japanese cities famous for their knife production, such as Sakai (in Osaka), Seki (in Gifu), and Echizen (in Fukui).

Because honyaki knives are forged from high-carbon steel, its blade is extremely hard and can be sharpened to incredibly thin and sharp edges that will remain sharp for a long time. However, they are challenging to resharpen and prone to chipping, cracking, or breaking if used improperly. Due to the small-scale production and the highly-skilled artisan nature of the blacksmiths, honyaki knives are more expensive, and recommended for experienced and professional chefs who can maintain them.

On the other hand, kasumi (“mist”) knives are made by joining together a piece of soft iron (jigane) with a piece of high-carbon steel (hagane) to create a laminated blade. After forging, hammering and shaping, the carbon steel (hagane) forms the core and cutting edge, while the soft iron (jigane) clads the body and spine of the blade. The hazy appearance of the soft iron in contrast with the glossy carbon steel gives kasumi its signature ‘mist’ appearance, as referenced by its name. Thanks to the added soft iron, kasumi blades have reduced brittleness overall, and are cheaper and easier to sharpen than honyaki knives.

In relation to kasumi knives, Hon Kasumi or Hongasumi knives are also commonly found, and refers to a higher grade of kasumi knives. Although Hongasumi knives are made in the same way as kasumi knives, they are often made from higher quality materials and involve extra attention and steps in its forging, tempering, polishing and finishing processes.

How to choose a Petty knife

If you’re in the market for a Petty knife, it can seem difficult to figure out which particular one will be perfect for you, especially if you haven’t had the chance to try out a few models in person to get a feel for what size and style of the Petty feels the most balanced and stable in your hand.

You can see our best recommendations here, but here are some factors to first consider that will help you to choose your Petty knife:

  • Types of steel
  • Handle styles
  • Ideal size
  • Your budget

Which steel should I choose for my Petty knife?

Generally speaking, you have a choice between carbon steel and stainless steel when buying a Petty knife. The type of steel you choose will determine the knife’s edge retention, how easy it is to sharpen, level of resistance to corrosion and rusting, and its overall durability. You can first evaluate which of these factors are the most important to you, and narrow it down from there.

Carbon-steel blades are easier to sharpen and maintain their sharp edges for longer, but require more maintenance as it is prone to rust and corrosion. Over time, a dark patina will form on a carbon-steel knife. Popular high-carbon steel options include White Steel (Shirogami) and Blue Steel (Aogami).

stainless steel blades are generally less expensive, tougher, less likely to chip and more corrosion-resistant, however are harder to sharpen and tend to dull quicker. Popular stainless steel options include VG-10, SG-2, AUS-10, Gingami #3 and Swedish stainless steel.

What size Petty knife should I buy?

We recommend the popular 120mm or 150mm blade lengths as the best size to get the most versatile usage out of your Petty knife. If you’re looking for a true paring knife to peel and slice vegetables and fruits or to do smaller delicate work, a Petty knife with 80-90mm blade length is recommended.

To help make your decision, you should consider factors such as the size of your workspace, the size of your hand, and the size of the produce that you will most commonly work with.

What is the best handle for a Petty knife?

The handle of your Petty knife will determine where the balance point is in your knife and how comfortable it feels to use in your hand.

Consider your usual grip on a knife. If you mostly hold the knife by the handle, a shaped or tapered Western-style handle will feel most comfortable and familiar to you. The balance point of a Petty knife with a western handle tends to be near the center of the blade.

If you hold the knife using a pinch grip, a Petty knife with a traditional Japanese-style handle (‘wa-handle’) will feel great in your hand. The most common wa-handle shapes are the D-shape, oval, or octagonal, and while some prefer the ergonomic grip of a D-shaped or octagonal handle, it all comes down to personal preference. The balance point of a Petty knife with a wa-handle knife is a little further forward towards the tip.
