This hand-forged petty presents the top level of Tojiro’s offer of multi-purpose, small kitchen knives. The excellent Aogami #2 core is hand-forged using the traditional method into a beautiful 21-layer Damascus pattern with black kuro-uchi patina.

The Petty design is intended for all those smaller tasks where larger knives are deemed unwieldy, both on and off the cutting board. A must-have knife in every kitchen, it can be used for peeling, mincing, paring and decorating food.

The core of the knife is Aogami #2 steel (one of the most regarded high-carbon steels), clad in two layers of softer layers of stainless steel (called san-mai clad). This is a great combination of two different types of steel - the outer layers will protect the blade from developing rust, and at the same time, we have top-notch steel for the cutting edge. Advantages of Aogami #2 steel are a very fine, gentle sharpness, it is easy to sharpen, and remains sharp for a long time. The lower part of the blade where the  Aogami #2 steel is exposed will develop some patina after time, so we recommend oiling the blade regularly in order to prevent the development of rust. Read more about how to take care of high carbon knives and patina in our Knife maintenance blog post.

The Kuro-uchi finish, the untreated upper part of the blade has an already-developed dark patina that protects the blade and gives it a traditional Japanese look.

This knife was fitted with a large, D-Shape, traditional Japanese wooden handle, made of magnolia wood with a Buffalo horn ferrule. Suitable for a demanding chef for home or professional use.

Made in Tojiro Atelier, known for elaborate custom-made knives.
