Quite true, but wouldn't you have a difficult time controlling the width of it's 'path'? If there were a really good way to 'set' the resulting width, I can see it being very useful to my process - if I could say I wanted a .003 line width out of the rotating scribe, and it were very uniform, it would certainly speed up my scratching process, even if I had to slow down the linear speed of the plotter head to let the scribe do it's work.

the rotary scribe would make a wider line.
