Good evening.
I've often read the suggestion that when one considers having a badly-out-of-polish or rusted blade polished, the blade should be given to a polisher to "open a window" to see if the blade is even worth polishing.
Do not worry, I have no intention of doing any polishing work myself or having non-trained amateurs do it. This is just a theoretical thread.
Now, I'd like to ask a few questions about this practice:
1. Is this commonly accepted/done?
2. To what degree is the window opened (base polish, full polish)?
3. What influence does a window have on a subsequent full-blade polish? I mean, won't the blade consequently be more tired in the area of the window? I doubt a polisher would polish "around" the window...
