My two cents..*Plink..plink*..
The Kabar Mule is tough as hell. I have had one, though lost it. The edge took and held a razor's edge, the point was strong enough to dig through a 2x4, which was alot of fun actually. I did split quite abit of wood with it, although the blade was kept unlocked. The hollow-grind edge with the fairly thick spine worked well. It's sheath held up well enough. I'd recommend the plain edge or the serrated, though. I ended up stepping on mine, dropping it in a fire, dropping a rock on it..dropping it from a tree..ah..well..s@#t happens. Upon wanting to test the thing, I hacked through some quartz and concrete, punched a hole through a 2x4, split wood (unlocked), punched (hammered) through a concrete block, battoned it through a 2x4, and to test it's edge holding capability (after restoring the edge, which was rather easy), turned a 2x4 at a foot long into slivers. It still shaved hair. Throughout all of that, the knife remained solid, and while i did have to work on the edge, and remove a few small chips, it performed far beyond my expectations for the price.
