You can't shank a fool with a hawk, but you can certainly crack their coconut.
Last weekend I went camping with two tools: a Frontier Hawk and a True Flight Thrower. I used both to chop up a bundle of wood for fun, and to have a warm campfire. The wood I purchased was arm sized, and I busted them up into finger sized kindling and made some shavings. I have a lot more experience with the Frontier hawk, and it did just fine with this. The True Flight I hadn't used for a decade, and it did surprisingly great! At 5mm thick, it batoned through straight grained wood with ease. I saved the gnarly grained pieces for the hawk, because I didn't care to work so hard to beat the knife through that stuff. The knife is a lot lighter than the hawk, though. I think it is quite capable for survival as well.
With enough time you can crack a coconut with a SAK.
