Used the Natural Outlaw last weekend to hack most of the way through a gnarled old tree root (about 2-1/2" or so thick). The NO is not very optimum for chopping, as is the case with all knives I have tried of that length. I had to choke way back on the handle to get much energy into the target. Despite the loss of control, using it with only two fingers and the thumb holding the end of the handle achieved almost passable momentum for chopping. It's not comfortable though. FWIW, the edges of the cut area were shaved extremely clean, not torn at all.
After we had pretty much chewed all the way through that tree root with the NO (and a couple of licks from a BM), the NO would still cut paper EASILY and semi-shaved. I never cease to be impressed with Busse edge holding ability.
While I think the Steel Heart is more of the ideal size for an all-around blade, the NO impressed me as a very fine carry knife. As a tactical field knife or hunter/camp blade I think it would work very well. For tactical fighters, my tastes tend toward a Randall #1 or maybe a Mad Dog, although I think Busse's INFI blades are tougher than either.
My quick $.02 worth. Stay sharp,
