JACKNIFE/ SCREWDRIVER HACK

Multiblade jacknifes are quite versatile until you need any thing other than a small philips or sraightblade screwdriver. This hack allows the knife to be used for any screwdriver bit in existence.

You'll need a multiblade jacknife, a hammer, a centre punch, a bit holder and a vise.

Put the bit holder in a vise with the hex side up. Use the punch and hammer to drive out the centre piece. Discard the centre piece. Slip the remaining holder over the can opener or bottle opener blade of the knife with the hex side facing out. It should hold securely. Put any bit in the holder and you're done.
