I was halfway down a mountain once and my binding came loose, no screwdrivers on me, nothing in the car, luckily a guy in the crew had one he could spare. From that day on, I vowed to carry a driver at least in my bag and after purchasing a small set, I saw an opportunity for a design.
Using the rubber O-rings that came with the packaging, I designed caps that would be protective in the event of a fall while skiing or snowboarding. Adding the Saturn like ring helps when taking the cap off in snowy conditions, most likely wearing gloves.
