Jerry, my biggest concern with a blade that large, especially as Close Quarters with other friendly people around is overtravel and maybe taking a chunk out of Mrs. Parker or my dog or my troop, etc.
I am at largest comfortable with a 10 inch blade, MDK Panther, weight about the same with the same mission profile.
Regardless of skil level there is always the neat effect of the big knife on the human eye and the guy receiving a view of that blade from the pointy end, and perhaps less skil is overcome by the bigger blade, but control is a factor too with the bigger blade. I do know a boxer with a seriously bent personality whose only preferred blade is a machete "so he can just go nuts with it."
Still all in all that is a seriously impressive knife/ sword/ pruning tool.
Tom, a khukri is a heavy tool with lots of momentum involved, good for whacking thru things but the recovery is very difficult without a lot of practice. Good tool/ weapon combo if it works for you tho.
