Don't think this exists yet but i think it should. There are a number of specialist tools out there, sometimes we buy them, sometimes we can't afford to. Is it worth having a on-going thread running where people can ask for specific tools and local people can respond?
Reason for suggesting this is because i am after one of these:
To tighten a very very awkward nut. I can't afford to go out and buy a full set at present, but, could really do with borrowing one to do one job. Anyone local in the South Derbyshire / Derby area who would be as kind to lend me one would be appreciated. Even willing to drive over, use it, hand it back and leave again if you don't want to loose sight of it!
Can't remember the size but will check when i get home
