Do your favored methods work on every razor.
No.. that would be too easy
or do you have to compensate and adjust?
Yup
I'm talking about changing stones in the progression, not just numbers of laps. And, if the most favored technique doesn't work fo all, why do you suppose not?
Can be any number of factors but here's one instance from my experience. You get a set of 2 identical wedges with ivory scales. One is properly tempered the other missed the tempering process all together & is hard as rock & chippy on your Shaptons. Now you can risk unpinning the ivory scales & throw it in the oven at the right temp to soften it back a little or you can try something like a coticule & see if you can sneak up on that edge. In this instance the coticule worked for me but some other stone may have done the trick too.
Do all razors of a particular brand or style resond the same to your efforts? And again, if not... Why not?
