I have a Tsprof on the way. Looking to see what stones and some feedback on the sharping systems that use 4 or 6 inch stones. Any one use a Tsprof? What are you using on the vanadium steels and other super steel. Looking at getting some diamond matrix stones as I have several vanadium knives always wondered why they lacked getting a great edge as they need a tough stone to cut the carbides. Will probably use my sic stones for the rest.
