We were talking about sharp b-heads a couple day ago and the importance of them. My question is if all is true why do they even produce serrated edge blades like such??? I always thought a rougher cut the more of a chance the wound has to clot and close up and prevent penetration??Am I wrong??

I know I have seen some more just cant find them????

You are correct in your understanding of the physiology of an arrow wound. However archers and bowhunters are gadget people. If it looks cool, someone will buy it. You have to admit, those serrated heads look way more deadly than the straight edged versions. Companies are in business to sell stuff.

I know that serrated edges do two things:
1. Eat up KE upon impact thus lessoning the likelyhood of a pass through shot.
2. If you hit the shoulder blade or rib, those serrated edges are going to catch thus lessoning the depth of impact.
I have seen them in action and you'll never find me shooting one.

The whole point of shooting a broadhead is to slice through the deer. If I wanted to saw through one I wouldnt be carring a bow to the woods, I be carring somthing like an echo or maybe a still chainsaw. No, in all seriousness Ive read several articles about how a deer will bleed more and has a much harder time clotting a clean cut hole compared to a tear, and all the serrated blade is doing is tearing/sawing through the deer. I think its just a gimmick to sell more.

Technically speaking it will stay sharper for a longer period of time.
Which I do not believe to be an issue when it comes to broadheads...unless a person can not afford to properly sharpen, replace blades, or buy new ones altogether.
Physics provides a clue for the reason why serrations tend to stay sharper longer than a straight knife edge. A circular shape is stronger than a straight line, which applies directly to the radius on the scallop vs. the straight knife edge design. A scallop edge tends not to fold under like a straight knife cutting edge. The edge of a serrated blade is also longer than that of a straight edged blade of the same overall length, therefore, an increased edge length is applied to the material being cut. This means that more material can be cut before the serrated edge is dulled.
Worthy to note is that you can actually get a straight edge too sharp. This might ridiculous at first, but the fact is what makes a straight edge first cut into an object is the same principle behind serrations. A straight edge blade must possess micro serrations to initially break through the surface of the object being cut. Field testing has shown that a perfectly honed and polished edge will shave the hair from your arm, but it will not easily slice through the surface of a tomato. Before any material can be cut through, the cutting edge must (first) be able to easily break through the surface. The ultimate straight edge not only must be sharp, but it must also possess "micro" serrations. These micro serrations are put onto a blade during the final sharpening (grinding) stage. Honing, buffing, and polishing the edge can remove them.

True, those micro serrations may aid in slicing through something but broadheads have a tip to start the hole and the blades will follow. Even with cut on contact style heads the head is stabbing the initial hole rather than slicing it.
