So I have the Norton 4K/8K and I'm looking for a bevel setting stone. Would you guys recommend the DMT Duo-Sharp or Dia Sharp and what's the difference between the two? Also what grits should I look for? I'm thinking 600/1200 or should I get a single grit stone? I would like it to cost under $80 so if DMT isn't the answer what do you think would be an alternative? Thanks in advance for your help gentlemen!
