Yeah, that was my original worry...with a choice between faults, I suppose the best choice is the one with no risk (do nothing). It's probably been there longer than I have been alive, so at least I can think about for a few years, and revisit if I have miraculously run out of other razors to work on.the two blades would be a different size and not match anymore. That would bug me.
Thanks for all of the input. I'm learning fast with all the great experience shared.
