Constant rubbing of anything in one spot will cause wear, you can strop a razor sharp with a leather strap or linen strop cloth. An aluminum or carbon fiber or brass rod rubbed into the same spot on the throat will wear over time. Most of us are not ambidextrous, nor are we set up so we can vary that angle very much, I can't even begin to properly brush or patch a barrel with my left hand!
You seek escape from pain. We seek the achievement of happiness. You exist for the sake of avoiding punishment. We exist for the sake of earning rewards. Threats will not make us function; fear is not our incentive. It is not death that we wish to avoid, but life that we wish to live. - John Galt
