Since tape measures seem to be a commonly lost item....
Been using the same one for 20+ years.
When I'm done with it- it goes back on the same spot on my tool belt where it has lived since I bought it (see below). If only I could keep track of the rest of the stuff this well. 
And after I had my own tools, I know why my dad used to yell at me all the time when I didn't put his back.
