broadhead edge
Pat B:
I think a smooth edge bleeds better than a rough edge. A rough edge has a tendency to clot quicker.
JEB:
I like that jagged edge. It will rip the hide and flesh. When I do use Zwickeys I use a file and leave a burr on the edge for that reason. I nip the edge of my stone points to put a serrated edge on them.
Mafort:
Depends on the animal I’m going after.
Hawkdancer:
If I remember correctly, there was a thread on this last fall or spring with some convincing evidence that a smooth sharp edge cut does not clot as fast as a jagged sharp edge cut. At least in the vital organs area. Shot placemement is still most very important!

Here was my contribution to that discussion. I think it was from one of Dr. Ashby's reports. Good reading if anyone wants to reaearch him.
--- Quote ---The 'rougher' a cutting edge is the more it mangles the
tissues, tearing rather than slicing cleanly. That means more
vessel-lining cells will be damaged, and the amount of
disruption to each damaged cell will be greater. The more cells damaged, and the greater the damage to each cell, the greater the amount of prothrombin released. The more prothrombin released, the more thrombin produced. The more thrombin there is, the more fibrinogen converted to fibrin. The more fibrin produced the shorter the clotting time. The shorter the clotting time, the sooner blood loss decreases and/or stops. The sooner the bleeding subsides, the less the total blood loss.
