Petty

Petty / utility knife with a 163 mm blade.

This model is relatively large and substantial compared with a traditional petty knife. The additional length makes it versatile for precision work, trimming meat and fish, preparing smaller vegetables, and other tasks where a full-sized chef’s knife feels unnecessarily large.

Ohishi Hiraki is a Japanese knife series made in Sanjo, one of Japan’s traditional centers of knife making. The blade features an SLD steel core laminated between stainless steel outer layers in a traditional sanmai construction.

SLD is a hard, wear-resistant tool steel with a high chromium content. It combines very good edge retention with relatively good corrosion resistance and is well suited to thin Japanese kitchen knives. The steel is hardened to approximately 62–63 HRC.

The blade has a tsuchime finish, with a hammered surface that gives the knife a distinctly Japanese appearance and creates a contrast with the smoother section closer to the edge.

The knife has a traditional D-shaped Japanese handle made from red sandalwood with a pakkawood bolster. The combination gives the knife a classic appearance and a secure feel in the hand.
