The handle is not round, but elliptical, same as a kabar, and nobody stabs with thumb against guard or more than a nail will be broken. Well, actually, you can....one time.

It is sold as a fighter, but being a consumer market knife, subject to many local laws, the top edge was left unsharpened, but of issue profile, and so, easy to sharpen, if desired. Folk wanting to club their knives like baby seals will be happy to save their clubs, meanwhile.

As for a fighter, or even field use, one "defect" easily remedied is that the knife has no instinctive way of determining in the dark whether edge is up or down. The elliptical shape will give you one or the other. A pinky/last finger can reach for the lanyard hole on pommel bottom, as a reference. Or, a notch or surface modification or whatever can be done to guard, even if only chamfering one rear hole in the guard.
