You often see them in mixers, there is a cap on the end
(usually colored) which you can CAREFULLY lever off, and
this reveals a brass screw, in the same axis as the pot shaft,
which as you rotate it (using a SPECIAL TOOL NOT SUPPLIED)
causes the knob assembly to ungrip the shaft.

Main advantage: you can get at it vertically, and there is no way
for the knob to be  eccentric.
Disadvantage: people get confused and try topull them off with
pliers and f*ck everything up.
