The ROBISON Bros bit is 'smooth' on one side of the portmouth and 'rough' on the other side. I may have been misled by the term 'reversible'. Both bits can be 'reversed'. What was the purpose of the 'rough' side? Thank you both a thousand times. One never graduates from 'the school of learning' or the 'school of hard knocks.'
