I bought my first fixed blade knife just before my last camping trip, a Buck Vanguard. When learning how to split wood by batoning, it snapped right off at the base of the tang after about 10 minutes. I was quite surprised at how narrow the tang was! I've since decided that a survival knife has to have more of a tang- not sure what it's called, but I'd call it a "full handle" tang, where the tang is the full outline of the handle, and the handle is basically two pieces on either side.
