Abstract
An expandable broadhead includes a number of fixed blades cumulating in a point, with each of the fixed blades having a channel for receiving a cammable deployable expansion blade, with the expansion blade having a slot which cooperates with a fixed retaining pin transverse to the channel that cams the deployable blade outwardly when a forward impact shoulder of the deployable blade strikes a target. This moves the blade relative to the fixed retaining pin and thus cams the deployable blade out to an expanded position for maximum blade cutting edge contact to effectuate maximum damage to the target and a quick kill.
