Actually,a serrated blade won't cause more tissue damage. It cuts through the same amount of tissue as a straight blade on the same path. However, it does leave ragged edges on the tissue it does go through. Since clotting has to start by attaching to a surface. The more surface area you have, the more opportunity to start clotting on the same size cut. A razor cut bleeds a long time, because it leaves relatively little surface toanchor clotting.
