Washing dishes with a headlamp while the electricity is off.



We needed to get some extra padlock keys made for when we have visitors.  We found this locksmith who held the original key in front of the blank, rested both on a rock, and then filed the new key with a hand file.  We had him make 3 copies and he charged $1.80 total.  When we got home, the original still worked and all 3 copies worked as well.
