The Hatsukokoro Blue #2 Rainbow Petty 150mm is crafted in Seki, Japan and features a striking near-mirror rainbow Damascus finish that really stands out in person. At its core is Blue #2 (Aogami #2) carbon steel, prized for its excellent edge retention, ease of sharpening, and crisp, responsive feel on the stones. The stainless cladding helps reduce maintenance while adding durability, and the ebony octagonal handle provides a comfortable, refined grip that complements the knife’s lightweight, nimble feel.
Blue #2 carbon steel is a favorite among enthusiasts for its ability to take an extremely fine edge and hold it through extended use. As with all carbon steels, it will develop a patina over time and should be dried after use to prevent rust. With proper care, this steel delivers outstanding performance and long-term edge quality.
Care Instructions: Hand wash and dry immediately after use. Do not leave the knife wet or in a damp environment. Avoid cutting hard or frozen foods. Use a soft wood or rubber cutting board to protect the edge. Carbon steel will naturally develop a patina with use.
