Out of idle curiosity I am interested in what kind of odd things people keep in their toolboxes or close by because they are particularly useful even though they were never designed to be used as tools. For example, I have become very fond of an old CX500 fork stanchion that works a treat as an extender bar for spanners and socket handles - ideal for those hard to move nuts and (so far) completely unbendable. What inventive uses have people found for other spare bits and pieces?
