CTS-XHP is a powder metallurgy steel. Any Carpenter knife steel grade name ending in "P" indicates Micro melt = power metallurgy. I normally explain CTS-XHP as powdered D2 with an extra 4% Chromium. I have been using a CTS-XHP hunting knife for 3 years now and it has performed extremely well. CPMS30v does have more Vanadium than CTS-XHP which should equate to better wear resistance but both steels perform extremely well. The upside to CTS-XHP would be ease of sharpening compared to S30V. You cannot go wrong with either steel !!!
