All I really need in a multi-tool is pliers (with wire cutters), a blade, file, saw, extra small/med/large flat screwdrivers (flat works for philips), a true awl, and scissors. I wouldn't mind a regular 1/4 style bit changer either since a lit of stuff today uses Torx, Allen robertson etc

I think you hit the nail on the head there, most if not all multi tools/knives come with one or more obsolite attachments.Perhaps the forum could come up with the ULTIMATE multitool SAK as designed us <img src="/images/graemlins/cool.gif" alt="" />
Just for fun of course <img src="/images/graemlins/grin.gif" alt="" /> ( although some forward thinking company may just take it seriously)
