No...and on rare occasions yes.
As Bruno pointed out, it's a tool and should be used rather than conserved. I agree for 99,9%
But the older and rarer a object becomes the more historical meaning it gains. I would be a shame to find a rare late 18th century razor and not approach it with historical courtesy. I would consider it a loss if such an artifact was vigorously regrind and rapidly honed into oblivion by someone with a severe case of honing fury. (God knows I am honing my razors far too often).
Bottom line, if an object has real historical significance, whether that be a Roman shovel, An Egyptian hairpin or George Washington's razor, it should be treated accordingly.
