I wanted two new keys to lock our apartment door.  No Wal-Mart so I sent my helper to the market and he had this fellow make one with a file, punch, hack saw, hammer, etc.  After several tries he came to the house so he could try them instead of my helper bringing them home, and taking them back when they didn’t work.  Here he is holding the key blank with his big toe and finger of one hand while running the file with the other hand!!  

A key in the making!
