What doesn't make sense about it? It's a cutting machine on steroids.

Why serrations? Because serrations improve cutting ability. The tips of the serrations provide single point penetration at the same time the center of effort rotates around each serration for an infinite number of cutting angles, increasing the cutting edge length by up to 24% (Diagram B). A serration is a sharpened recessed curve along the edge of the blade and has more linear cutting surface than a straight edge in the same space (Diagram A). And, serrations improve edge retention because the tips initiate the cut easing the amount of force required by the recessed edges. The points actually protect the sharp inside curves that continue the cut, thus the curves have less wear over time.
