Have to admit, having read this thread I`m pissing myself laughing, really don't get it.

However, many years ago I acquired a short piece of very heavy duty rubber high pressure hose which fitted nicely in the palm of the hand, it had been taken as a sample for chemical compatibility testing by one of our engineers and never got used. I used it as a stress ball at work, it took much effort to compress it and it became a fixture on my desk. When I finished work I took it home as a keepsake and I now use it on my watch bench to support workpieces whilst doing refinishing work! I use it to tape bracelets around when refinishing, the curvature makes it ideal for this task and I`d struggle without it.
