This probably sounds obsessive, but I recorded myself sharpening with a diamond stone to see if I'm doing it right. My skiing buddy seems to think I'm going to run out of edges in a year because of how much I sharpen. I'm not sure if he's joking or not, but I know that's ridiculous.
So in the video, I'm wetting the stone, then wetting the edge, taking one light pass to spread the solution, and then taking the real pass to sharpen. After doing that I clean the edge with a dry and then wet paper towel.
My last serious sharpening job was pretty bad, so I did this type of pass twice with a 100 grit stone, six times with a 200 grit (by this time I was starting to get nailed filings) and then I think twice with a 400 grit. Also focusing a bit more where there was serious damage, and maybe doing an extra pass only underfoot. So am I spending enough or too much time for each pass? Am I doing enough or too many passes?
Oh well, I guess I'll chime in with my video seires. Nemesis this is basic tuning. It might help you.
