Personally, I'd go for a Victorinox One-Handed Trekker, or one of the Wenger Ranger models. A little bit bulky, but over time you'll never notice the extra tools are there until you need them. I know it's a little bit of a one-ended argument here from me but I've been carrying a SAK as well as a CKRT M16 model for quite some time. Both have yet to fail me, and I think they won't, not for a long while anyway.
