This 15 function multi-tool from Frog Tool seems like it can do anything. Definitely something to throw in the glove-box or desk drawer for an impromptu situation. Just check out all that the stainless steel tool can do. Plus, at only $4.99, it would make a great stocking stuffer.

While it’s obviously a good price, think if the time it would take to memorize all its uses!
