Hello all,
As I've mentioned elsewhere on this forum, I recently honed an old vintage straight razor. The honing/polishing I did using the pyramid method. I'm pleased that all the hard work paid off, but now that I have one under the belt, I want to advance myself by learning about progression honing.
I understand it's removing the scratches from the previous grit before moving up, but how do you know exactly when you are ready to move up?
