Another very important effect of razor sharp blades is not only that they will penetrate better and cut arteries, but also that razor sharp blades, on a microscopic level, create a very clean straight cut through tissue, where a dull blade will create a jagged wound. This clean cut helps greatly slow the clotting response because the clotting agents in the blood(platelets)don't have anything to grab ahold of as they flow into the wound. This allows the blood to flow fasterand for a longer period of time before clotting significantly reduces bleeding, thus maximizingthe chances that the animal will bleed out. A dull blade that creates a jagged (microscopically) cut will allow for faster clotting and increase the distancea fatally wounded animal can run before their circulatory system shuts down from blood loss.It also greatlyincreases the chances that a marginally hit animal will not bleed out fatally andmay be lost due to a lack of a followable blood trail and might suffer a prolongeddeath due to infection and such.

Bottom line? Hunt with sharpbroadheads, as there is really no excuse not to.Most broadheadshave easily replaceable blades, and thecostof such blades arerelatively low.And ifone cannot replace the blades, then sharpening/lapping devices are cheap, reusable and readily available and it would be prudent for someone whocannot replace their bladesto learn tosharpen them.
