Did he use shoelaces more than the one time in "Partners"? I can't remember any other instance, but my brain's hurting right now anyway . . .
Certainly he used string often enough (shoelaces, sleeping bag cord, etc.), not to mention rope (lasso, slack-rope walking, etc.).
He also used light bulbs at least three times that I can recall offhand: at least twice to provide the spark for an explosion, once to make a lockpick.
