Bugs3X, the Chinook was designed by James Keating, who is a leading proponent of the Bowie knife in knife fighting. And one of the techniques that he emphasizes in using the Bowie, especially one like a Bagwell Hells Belle, is the "back cut," which is a sort of wrist flick bringing the blade back after you have finished a forward slash with the regular edge. The back cut uses the false edge or swedge and the point and, according to Keating, can inflict terrible damage if done right. I have read that the point and swedge on the Chinook were designed with the back cut in mind, and, if you look at the blade, it is clearly descended from the Bowie, so I would believe it. I suspect that you would have to sharpen the swedge to maximize the effectiveness of this, but I may be mistaken in that. But do remember that the fighting style for Bowies was essentially a slashing style, not a thrusting style, so I would further suggest that this is the style for which the Chinook is maximized as a fighting knife.
