I dont own any such knives, cause I want much more utility for survival. I use the Cold steel shovel, without a handle as a "big knife" and a highly modified Crunch multitool, with saw blades to be held in the visegrip of the tool. No knife can come even remotely close to what this combo can do. I can make any length or type of handle needed for the shovel in an hour, which lets it replace an axe, machete,etc.. It can be a paddle, a spear, an adze/hoe. The Crunch has a scoop/gouge blade, a couple of files, a chisel point, a regular carbon steel knife blade, a drill/awl. The very ends of the jaws are ground down to needlenose configuration, too.
