When a Small Tool Transforms the Way You Cook

“Bigger is better” doesn’t always hold true—especially in the kitchen. In culinary work, it’s often the smallest tools that perform the most delicate, essential tasks.

Whether you’re peeling fruit, garnishing, or mincing herbs, the petty knife proves itself indispensable. Compact yet powerful, this “small giant” offers incredible precision and reflects the best of Japanese knife-making in every detail.

What Is a Petty Knife?

The word “petty” comes from the French “petit,” meaning “small.” With a typical blade length of 120–150mm, petty knives excel at detail-oriented prep—peeling citrus, trimming vegetables, mincing herbs, or prepping small fish.

It bridges the gap between a paring knife and a full-sized Santoku or Gyuto—an essential sidekick in any kitchen.

Key Features

• Blade length: 120–150mm
• Edge shape: Straight with a pointed tip
• Usage: Peeling, trimming, garnishing, small fish prep
• Handling: Lightweight, maneuverable, ideal for tight spaces

Where the Petty Knife Shines

Loved by both professionals and home cooks, the petty knife is a powerhouse of versatility:

• Peeling apples and citrus
• Removing tomato stems or skins
• Mincing herbs and garlic
• Filleting small fish
• Preparing bite-sized food for children

It’s indispensable in Japanese cuisine and equally valuable for Western plating and pastry work where finesse is key.
