Definitely a very worthwhile multi-tool, but I seldom carry mine as the only mult-tool, usually as a secondary one. The Crunch has a lot of clamping force and the vise-grip action, which is pretty unique and handy (only comparable one I know of is the Vise-Grip tool which is a lot bigger), but is very limited on its other tools. In addition to the pliers, it only has a short serrated blade, file, two regular and a philips screwdriver, and all are locking. Unless you specifically need the extra clamping force and locking vise-grip action, I wouldn't buy it to use as your only multi-tool. As a supplementery tool, it is great though, doing some things a regular Leatherman could never do.
