If your a tool junky, then i'm just crazy.
Lets see I have or had (and i'm sure I missed a few):
Charge Ti
Surge
2 Old Waves (one was a gift from Tim Leatherman, oddly they are both slightly different)
Kick (with clip)
Blast
4 Juice models (Pro, KF4, CS4, KF4 Gray)
Original PST
PST II
Crunch
Sideclip
Micra (which I turned into a single sided tool)
Super Tool
3 Squirts (P4 and 2 S4s)
2 Swiss Tools (BSA Model)
Swiss Tool Spirit (on the way)
Gerber Suspension
Gerber Compact Sport
Gerber 600
Gerber Recoil
Sog Switchplier
Sog Powerlock
Sog Pocketplier
As well as a bunch of cheap knock-offs
I also hae the tool kits, clips, sheaths, you name it.
The ones I like the most are the Charge Ti, Surge, Juice KF4, old wave, and Sideclip. The Gerber Suspension I just bought and I don't think there is a better tool out there for the price, I really like that one now too. The worst two are the automatics. The Sog doesn't open all the way all the time and I could break it if I sqeeze too hard and the Gerber has basically useless tools in it and the pliers don't open very much. I'm not a big fan of the Powerlock either for a few reasons.
