I've got a commercial grade barber shop one from the oldest barber in the state. They do make a difference.
I'm slowly trying to learn how to use a straight razor for shaving and using the soap cup and brush method now. They are all ancient collectable heirlooms.
Lots of local history back when men would go to the barber for a man's haircut and shave. The straight razor was replaced with the disposable single use safety razor in the 80s.
