The Huntsman one of my top three favorites.

Huntsman: scissors + saw
Climber: just the scissors
Camper: just the saw

Of course all three have additonal blades (knives, awl, corkscrew, can opener, screwdriver, ....), but these are the differences. For me the can opener, awl, tweezers, and scissors were must-haves.

My favorite right now is the glow-in-the-dark StayGlow Yellow Climber from http://www.knifecenter.com . I don't have a great need for a saw blade since I carry a Pocket Chainsaw in my bag.
