Forgot two of the reasons I like the SOG Paratool.
1. The pliers don't open in the same axis that the tool unfolds. This means that even if the tool hinges get loose, the tool is less likely to try to fold up on you while you're using the pliers.
2. The handles, when open, present the closed side to the user's hands. On a number of multi-tool designs, when using the pliers, the user's hands are pressing on the handles on the side where the tools fold out. This is not an ideal surface to apply significant pressure.
The Gerber tool, by the way, shares these two features albeit via a different design. I chose the SOG over the Gerber because it is a smaller and more "friendly" package when folded. Also, I vaguely recall, the Gerber pinching me really badly a couple of times while I was using the pliers before I finally gave it away. The big advantage of the Gerber is that it's very easy to deploy the pliers one-handed.
