Tosa Tsuboya Petty 120mm Damascus Tsuchime

Product description

This Japanese Petty kitchen knife is a compact and precise tool designed for detailed work in the kitchen. It comes from the traditional Tosa region and is manufactured under the Tosa Tsuboya Hamono brand, known for its authentic craftsmanship.

The blade is made of modern stainless cobalt steel, which offers high hardness, very good edge retention, and corrosion resistance. Thanks to this combination, the knife is suitable for everyday use without demanding maintenance.

The blade surface features both decorative and functional Damascus layering in combination with a tsuchime (hammered finish) treatment. This structure not only enhances the visual character of the knife but also improves food release during cutting.

The Petty shape is ideal for smaller, precise tasks such as cleaning, slicing smaller ingredients, or in-hand work. Due to its maneuverability, it is suitable as an addition to larger kitchen knives.
