I have lapped and re hydrated just about every barber hone I have acquired. The only ones that have been damaged by lapping were Sears Craftsman BHs. I have destroyed three of those (yep kind of a slow learner). Every other of the 50 or so BHs from lakesides to panamas to swattys to aparts, to rubys etc have done just fine and been brought back to life. having said that I agree completely with the starting principle of if it ain't broke don't fix it. If the hone works as is leave it alone.
