Excerpt from Popular Mechanics: Shop Notes, Volume 16, 1920.
Door
Knobs Make Convenient Handles for Bits
An excellent handle for boring bits, screwdrivers, and similar
tools, for use in cramped places, is a discarded doorknob.
For occasional use it will be found satisfactory to use the
knob without any alteration, simply inserting the bit into
the socket and tightening with the screw. The bit has a tendency
to wobble slightly, but otherwise is held securely. By beveling
off the end of the hole in conformity with the shape of the
bit shanks, or by filing off the shanks to an even thickness,
a perfect fit is obtained.
