It's not only PTFE tape that I spread around in copious quantities, other notables on the list are screwdrivers (of various sizes and types), superglue tubes (they go off with age anyway), propelling pencil leads, keys, USB and computer cables, USB pen drives, computer mice, adhesive tape, remote controls and any number of useful things.
The trouble is these supposedly inanimate objects come to life in the middle of the night and conspire not to be available when I most need them. Then the moment I've made do by jerry-built means they suddenly reappear! ;-)
