The present invention is a rear-deploying broadhead with a body that is attachable to an arrow shaft. The body has an inner portion and an outer cylinder, with the inner portion being disposed within the outer cylinder when the broadhead is in a nondeployed position. The inner portion has a solid internal shaft, a head, and an inner cylinder. The internal shaft is disposed in a position forward to the head of the broadhead, and is situated substantially in the center of the inner portion and movable within the inner cylinder in a plunger-like manner. The solid internal shaft terminates within the inner cylinder and is attached proximate its termination to an internal sleeve, and at least two blades are pivotally attached to the internal sleeve. The outer cylinder comprises slots there-through adapted for deployment of blades.
