What Is a Petty Knife?
A Petty knife is a small Japanese utility knife designed for precise, detailed kitchen work. Its compact blade makes it ideal for trimming, peeling, slicing small ingredients, and tasks that feel awkward with a larger chef’s knife.

Small & Precise
The compact blade offers excellent control for detailed cutting, trimming, and other precision tasks.
Versatile Utility Knife
A Petty works well for fruit, herbs, small vegetables, boneless meat, and many everyday prep tasks.
Easy to Handle
Its light weight and shorter blade make it comfortable to use when a larger knife feels unnecessary or cumbersome.
Who Should Buy a Petty?
A Petty may be right for you if you want:
PRECISION
Detailed Cutting
A great choice for trimming, peeling, and other small tasks that require more control than a larger knife.
SMALL PREP
Ideal for Small Ingredients
Its compact blade works especially well for fruit, herbs, garlic, shallots, and other smaller ingredients.
SECOND KNIFE
A Useful Companion Knife
A Petty pairs well with a Gyuto or Santoku for tasks where a full-size chef’s knife feels too large.
How to Choose a Petty
Focus on four key factors when choosing a Petty: blade length, steel type, blade shape, and handle & balance.
01 / SIZE
Blade Length
Petty knives commonly range from 120mm to 150mm. A 120mm blade offers maximum control, while 150mm provides more versatility for everyday prep.
02 / STEEL
Steel Type
Stainless steel is easier to maintain, while carbon steel can take a very sharp edge but requires more careful cleaning and drying.
03 / SHAPE
Blade Shape
A narrow blade with a pointed tip is useful for precise trimming, slicing, and detailed cutting around small ingredients.
04 / HANDLE
Handle & Balance
Wa handles are often lighter, while Western-style handles can feel heavier and more familiar. Choose a balance that feels comfortable for precise work.
Petty vs Santoku: What’s the Difference?
Petty and Santoku knives serve different roles in the kitchen: a Petty focuses on small, precise tasks, while a Santoku is designed for general everyday preparation.
