In my experience, geeks like multi-tools – they’re useful. Personally I always carry my Victorinox Swiss Army CyberTool 41 in my pocket and it has come in handy many times. And I have a Leatherman multi-tool that I usually have in my kit bag. This SOG PowerLock EOD Multi-Tool with Leather Sheath is similar to my Leatherman, a useful tool to have. And a pretty good deal at $39.99 + $5 S&H.
