DBS Double Ball Stylus, .045 in and .072 in Balls

DBS is Kemper's double ball stylus, with a ball at each end - one .045 inch across, the other .072 inch. A ball stylus presses rather than cuts, so it leaves a rounded impression with no burr to clean up afterwards. That is what makes it the tool for dotted patterns, eyes on a figure, and the small rounded hollows that a pointed tool cannot make without tearing. Two sizes on one shaft means the scale change is a flip of the wrist rather than a swap.
