Stropping on stones was meant. And indeed, 30 degree inclusive with the very edge is too steep with this stuff.
I assume you strop on a fine stone? Say 5000 or so? Does the stropping on the stone give a very different edge to using a micro-bevel?
Is it ok to have a 15dps (or even less) edge if you put a microbevel on? Is that is what you meant when you said don't let the knife ger too thick behind the edge?
