Swhacker broadheads are the best expandable broadheads because of their two-slice technology. The wingblades of the Swhacker broadheads take all the punishment as they cut through the first layer of hide, fat and bone. As the wingblades pass through this first layer, they cause the razor-sharp main blades to open inside the body cavity of the game animal. This two-slice technology allows the main blades to stay surgically sharp and undamaged, opening to their full cutting diameter as they slice through internal organs, creating massive internal hemorrhaging and an unmistakable blood trail. The ferrules are made from aircraft aluminum for durability, and the stainless-steel main blades are surgically sharp right out of the package and ready to hunt.
