Petty Knife Blank

The 130mm petty knife blank is a versatile Japanese utility blade designed for everyday kitchen tasks. At just 47g, it offers a perfect balance of light handling and durability, making it an essential foundation for a custom‑made knife.

Unlike a paring knife, which is mainly for peeling and fine detail, the petty knife excels at small to medium prep work — slicing citrus, trimming herbs, portioning cheese, or handling proteins where a chef’s knife feels oversized. Its 130mm blade length makes it the go‑to “in‑between” knife for both home cooks and professionals.
