I'm thinking of getting two of these for my kits. I have a small urban kit and a small kit for outdoors. I carry a swiss army pocketknife (with saw, hacksaw/file, pliers etc) in my outdoor kit, although the pliers are more akin to robust tweezers; awesome for small stuff. In my urban kit I've just got a swiss card. This xs (4", 100mm) hasn't been out for long. They also have a pliers wrench model, but that doesn't seem as versatile.
