Blue Steel #2 with a hardness on the Rockwell scale of 63 to 64, is forged with iron to create beautiful mist patterns, and an emphasis is placed on refined forging and polishing with the highest attention to detail. Handcrafted in Japan with traditional techniques, our Usuba has a completely flat grind on the front side (Shinogi), a concave grind (Urasuki), and a flat rim (Uraoshi) on the back. The combination of the Urasuki and Shinogi allow for the blade to cut food with minimal damage to the surface and cells, therefore not spoiling the texture and taste. The Uraoshi is the thin, flat rim that surrounds the Urasuki and enhances the strength of the blade at its otherwise vulnerable edges.Proudly made in Japan and not mass produced. This knife is complimented with a traditional Japanese Wa-style handcrafted Octagonal Handle that is lightweight and ergonomically welds to the hand for seamless use. A protective wooden sheath called a Saya is included, which protects the knife and adds to its appearance when not in use. TTraditional Japanese knife making values a sharp edge, which requires attention and care. Sharpening and honing should be done with only water whetstones. Hand wash and dry only, and do so immediately if working with acidic ingredients. Do not use on objects such as bones, nutshells, and frozen foods. Carbon steel can oxidize if not properly maintained. Keep dry and oil regularly to prevent oxidation.
