Title: Diamond doesn't polish the edge

I applied 5 micron diamond paste on the Tormek leather wheel.(Tormek paste is 3 micron)

But It doesn't polish the edge. What did I do wrong?

Diamond and CBN based compounds cause deep and narrow scratches on the edge bevels, while conventional abrasives (aluminium oxide, silicon carbide, chromium oxide etc) – shallow; when mirror finish is the goal, bevels should be honed with conventional abrasives.

BTW, if yo are not happy with the honing compound on your leather wheel, you can change it by removing with WD-40 and lots of rags

Thank you wootz.

But it doesn't remove even 1000 grit scratches as well as its color hardly changes.(blue -> black)

As you know, with the same 5 micron diamond paste, the paper wheel polishes edge.

so, IMHO, I don't think this diamond paste is suitable for Tormek leather wheel.

Sure, that's the way it is.
By my experience, leather works well with diamonds up to 2-3 microns, while paper wheels up to 10 microns.
