Petty - Utility Knife Small knives for all occasions
There are tasks in the kitchen where reaching for your chef's knife feels like using a sledgehammer. Small petty knives give much more precision and control for tasks like peeling, cutting fruits and trimming vegetables. They can also be used for small boning tasks like quail. Segmenting a citrus, trimming sinew or skin from a fillet, peeling a shallot, cutting the eyes out of a pineapple. The Petty exists for exactly those moments.
The Petty is a compact double-bevel utility knife, typically ranging from 120mm to 150mm. The profile mirrors a Gyuto in miniature - a gentle curve, a pointed tip, a thin grind - which makes it precise and nimble in tight spaces where a larger blade would be unwieldy or unsafe. It's sometimes called a utility knife in Western contexts, but the Japanese Petty is significantly thinner and sharper than most Western utility knives, which makes it considerably more capable.
It suits both home cooks and professional chefs as an additional knife. For home cooks it handles the detailed work that falls between a chef's knife and a paring knife - tasks that need a little more length than a paring knife but more control than a Gyuto. In a professional kitchen it's a constant presence on the line for trimming, portioning, and finishing work.
Compared to a paring knife, the Petty is longer and more versatile - it can be used on a board or in-hand depending on the task. Compared to a Gyuto or Santoku, it's a specialist for small, precise work rather than primary prep. Most cooks who own a Petty wonder how they managed without one.
When choosing, a 150mm is the most versatile length for general use. A 120mm suits in-hand work and detailed tasks. Longer than 180mm starts to overlap with a small Gyuto and is better suited to professional use. Stainless steel is the practical choice, though carbon options are available for those who prefer them.
The Petty won't replace your primary knife, but it will cover many tasks your primary knife handles poorly.
