i have a big glass hand held magnifying glass in the tools,bloody handy once ya get a bit older,see jets numbers or score marks etc,i also have a set of weirdo bits that fit weirdo screws that weirdos dont want you to undo,i got it free when i bought a decent multimeter years ago,been handy!also a few custom made bent/buggered and modified tools to suit certain things,im sure you can buy the real ones but wheres the fun in that?that little bent 6 side ring lets you bleed rear drums on Holdens with wide wheels without taking the wheels off,this bent 9/16 ring with the 1/2 drive socket head unlocks the dissy holding bolt on V8 Holdens with the dissy right hard against the fire wall like chevys have,these 1/2 drive sockets cut into fingers undo the clutches on a few chainsaws,too easy.
