Many of my first power tools were really junk when I got them and they certainly were after I used them to death.
I keep them for loaners and never loan my good ones.
Even then I have a sign-out sheet by the shop door and everything gets logged out and in. I started this after one too many times that I wasted an hour or two looking for a tool only to call my son in desperation and hear him say "Oh ya, I think I've got that". The list isn't needed much now that he moved out of state.
