knife is more versatile that an axe. It's more compact & easy to pack.
for chopping ?...not in my humble opinion...
No, all around general use. Easier to skin an animal with, make traps, whittle, etc. For only chopping though, where weight is not an issue, an axe is hard to beat. <img src="/ubbthreads/images/graemlins/thumbup.gif" alt="" />
