i wouldnt get too excited about the 'swiss army' aspect of my soldering iron. The only things from it I use are the long needle-like iron tip and the stand. The arms broke off it almost instantly (but I have a proper metal set of extra hand croc clip things - very, very handy). Its a decent iron though.
I have a dremel gas soldering iron/blowtorch as well - its a psychopath; the heat from the vents on minimum setting wll strip cladding off any wire within an inch off them. Very good tool, but overkill for guitar electronics.
