Danged if I didn't pay a lot of money for those dumb college credits I don't use, but every biology course I took made the point that a clean cut will continue to bleed longer than a ragged cut.
Stands to biological rationale that if you cut a critter with a raggedy edge file sharp blade that tears the edges of the veins, arteries and venules, it's going to "clot up" faster than ones cut with a polished edge, given they're both the same "sharpness" if that is possible.
Now having said that, I've seen near wars started over that question so I'm going to duck and cover!
:eek:
