Leatherman Charge Ti with a 154-CM clip blade clipped inside my pocket for about 6 years now. If I want a toothpick or a wine-bottle opener, I also stick one of my several Victorinox pocket knives in a pocket. In the field (wildlife, fisheries biologist), I've been carrying a Busse Hell Razor sheath knife since it was made in 2005 or 2006. The Leatherman is a really well-made durable tool, the Victorinox are proven, easy to sharpen and well-thought-out, and the Busse HR is expensive, but very well designed: good point, multiple choke-up options, digs if needed, can be used as a draw-knife for quickly making tinder, skins, cleans fish, doesn't rust, keeps an edge. -- Lots and lots of good knives out there, but these fit me.
