The Leatherman Micra is the greatest mini-tool I have encountered so far (@51 grams). I always have one in my pocket AND in my hiking pack. NOTHING I have discovered is as good for cutting one’s toe-nails – a vital safety precaution on multi-day hikes when toe-nail problems can lead to disaster! http://www.leatherman.com/20.html If you want to skip a few features you might go for their skeletonised version: http://www.leatherman.com/24.html#start=21
