X-7 steel is harder than German steel which allows it to take a significantly sharper edge. This proprietary steel was created by Cangshan to have the same hardness as VG10 steel without the brittleness while still retaining a high stain resistance. A unique, Damascus pattern is formed in the metal from folding 67 layers of steel together. X-7 Steel has a hardness rating of 60 ±2 on the Rockwell Hardness Scale.
