SK4 High Carbon Japanese Usuba

Our Usuba is hand-forged in Sakai near Osaka in, Japan, from SK4 high carbon steel, a steel prized for its exceptional sharpness, durability, and ability to hold a fine edge through years of use. THE BLADE The Japanese Usuba (meaning "thin blade") is a traditional, peeler vegetable knife favoured by professional chefs. It is specifically designed for precision tasks like peeling, intricate carving and preparation of all food types. Hand Forged in Sakai from SK4 carbon steel and hardened to HRC 62, this blade offers impressive edge retention and performance. As with all high carbon steel knives, it will naturally develop a patina over time, a mark of use that many owners come to appreciate. Just be sure to dry it after every use, as prolonged exposure to moisture can cause rust. The blade is finished with a traditional Blacksmiths Kurouchi finish, a dark protective layer that highlights the knife's forged character while reflecting generations of Japanese blacksmithing expertise. The makers mark is hand stamped on the blade in Kanji. THE HANDLE The handle is where this knife becomes something truly special. This Usuba comes with our slightly smaller handle which gives better balance to the smaller blade. Made by us here in Scotland, each handle begins life as discarded fish boxes collected through our Scottish Harbour Collection Programme. The plastic is recovered, cleaned, shredded, and remoulded into a durable handle with a distinctive marbled finish. The result is simple: no two knives are ever the same. Your new knife is presented in a gift box and wrapped in traditional Japanese newspaper, Available in Navy Blue, Green, Orange.
