I know it's been a while but once again when I have a knife question this forum is where I go for advice. I've gotten back into rock climbing and rapelling recently and need a light knife that I can clip on to my gear. I'm not talking about pocket clips, more like hook clips I guess. My climbing instructor carries a Kershaw carabiner knife that also has a screw driver and can opener but I've also been looking at the Buck Revolution. Any of you knifeknuts have any opinions on the subject? I'm especially interested in how AUS6 (Kershaw) compares to 420HC (Buck). Also if there are any other options I'd love to hear them. Thanks in advance.
