Leatherman Micra - makes a handy key fob. Used it many times to save my bacon out in the field. Think it was something like $5 on sale. Bought a few and spread them around. Found my first Leatherman in 1993. I bought one for everyone on my staff. The micra can help you pick a padlock using any aluminum soda can. YouTube “pick a padlock” and you will see how easy it is to do to any key or combo lock.
