Last thing I used mine for was adjusting the door closer on the office door. Went from a teeth jarring, door frame threatening slam to a satisfying shoosh-clunk. Leatherman wave.
To be honest, there’s a million (well maybe not quite a million) little jobs that I use it for that I wouldn’t have considered attempting without a leatherman on my work belt; I’d just have to book estates to come and sort it. So my leatherman is used for saving the NHS literally thousands hundreds some quid.
Edit; cme to think of it, our building is maintained by a PFI type of thing, so probably MEEEELLIONS!
