I did have an old set of wheels that were leaving a very polished surface on the tools, and decided to do an experiment. I tool aluminum, copper, brass, and some mild steel and sharpened until there were highly visible lines on the wheels. I went back to sharpening normally. After maybe a month, there was no visible trace of those lines on the wheels. I also did have some old diamond plates from DMT, maybe the first ones they put out, but the diamond plates had a bunch of holes in them, and were mounted on plastic bases. They had pretty much stopped cutting. I put some of the Trend Lapping fluid on them and they came back, not as good as new, but for sure, useable. I did try the Slick Stick on my wheels and I do think it is just too thick. I do love it on bandsaw blades to help keep gunk from building up when cutting sloppy wet wood. It is good on for a general lube on a lot of things, and it is the best thing I have found for the soles of my hand planes, FAR better than paraffin or any other wax I have used.

The wheels from Austria were the "Optigrind". I think Cindy Drozda was selling them after the owner passed away. Not sure if she does any more or not.
