Gents, I've reached a plateau, and it's a good thing. I have 3 jnats and a coti I noodle around with, typically rehoning the razor a couple of times a week. Note: I realize this is excessive, I'm skill building.
The plateau is: I can now get virtually the same edge off of all the stones, every time.
Now, I think, I'm ready to move to the next stage, which an edge better than my current achievement of "pretty good".
