The central core material SKD12 (high carbon high chromium alloy tool steel) used for the blade edge is a high-performance steel that, like SKD11, is extremely rich in carbon and alloy elements. It is hardened to around Rockwell 62–64, providing excellent sharpness, long-lasting edge retention, and high wear resistance.
