Carrying a Swiss Army knife on your Keychain. This is the climber version. You would be surprised but it's hard to find ones that have both the scissors and the cork screw, which in my opinion are necessary to have at all times!

I think it depends on the person, I need the reamer and can open on my Swiss Army knives and never needed the scissors or cork screw. I carry the Wenger Basic Issue or I think the Victorinox equivalent is the pioneer 
Definitely like the screw driver and bottle and can opener as well. Cork screw for reasons below. Plus I also carry the eye glass screw driver that nests in the cork screw (had to order separately) also the tweezers are handy and the tooth pick I do use occasionally. The only tool I think is worthless on this model is the package hook.
