i have both of the knives that you speak of . the ka-bar sucks , you cant baton with it[sharpened top edge] , it doesnt chop [too light],and it has a miserable excuse for a tang . in comparison the bk7 out performs in terms of durability, chopping and batoning . i also have a ranger rd7 and it outperforms all of the above by a long shot . if you use a fixed blade long enough youll probably start to appreciate the larger handles in hard use . the slightly ovalized handles of the ka-bar tend to role around a little in the hand and can be a pain while chopping espessially. the bk7 chops better than what you might think , even better if you re-profile the edge a little thinner . itll serve you well im sure . gotta try the rd series from ranger man , they are truly awesome.
