Yep, the heel of my boot is just as soft as a cork knocker, and I don't have any issues with my pipes being damaged by such. However, I am not about to clunk a pipe on a brick, rock, or the side of a building, unless it's a cork building, ha ha. To me, whether it is a Becker, Dunhill, or a cheap-ass Icarus, I bang 'em. I bang 'em, love 'em, and treasure 'em. They are mine till they pile my tobacco cellar and collection of pipes on my pyre and send them off with me into the great unknown.
You can do what you want to your own pipes.
