I just touch up my tools on diamond hones. The flat ones like a sharpening stone. Works well for me and saves HSS tool. My tools should last me a very long time if I keep them off the grinder. I will grind on a dry grinder if I really have to. That usually means my parting tools. Being a machinist for years I've ground more tool steel than I could pick up and carry. It's an art that comes in handy for my woodturning tools when needed. BTW, I finally got moved last week. No shop set up yet but I do have a nice detached garage with all my tools waiting to be unpacked, assembled (yes, I saved most of the boxes my power tools came in) and tested. I hope to be at least fuctional again in a week or two.
