the spur ( wide) keeps from getting the "proper" polish direction on the Super hammers, and if you put it on the edge and 'stop', you can and will get and "see" this stop/go/return' change in directions on any of them that have been polished that way....look at it with a GOOD light...thats what refinish and restorarion folks look for on any "questionable" gun as to it being redone or not........learned this from one of the old time "Master" Colt Python builders back in the late 60's.............. :wink:
yes, a flat hammer, for ANY other model can be done that way, heck ,even on a " fine" belt sander, takes about 3-4 seconds to do one....... :roll:
aluminum oxide paper gives an even NICER polish/finish........... 8)
