Only if you're a complete spaz. I've never had any trouble finding two
nearly adjacent holes for the tommy bars, allowing them to be easily
manipulated by only one hand. Much easier than chopsticks and a quarter
of the world has no trouble with those...


Even easier when you let the weight of the piece rest on your third hand -
the tailstock.

Wouldn't that be nearer a half than a quarter, even given modernization?
