I disagree with the statements about tearing being better! When flesh is torn the brain sends a message to produce clotting...when tearing of tissue occurs there is more rough edges for clots to stick to and thus the blood my stop flowing earlier than with a conventional head. A straight blade cuts clean and clots don't stick well because there is little to grab hold of.

Ever trail a deer and find a huge clot on the ground? The clot literally pours out onto the ground.

Everyone is entitled to thier opinions!
