Abstract:
A hunting arrowhead with one broadhead and two extendable blades for attachment to an arrow shaft, comprising:(a) a generally tubular-shaped body with a tip end, a shaft end, and an outer surface,(b) four parallel, longitudinal and non-communicating troughs spaced at intervals about the outer surface of said body, thereby forming two pairs of opposed troughs, a first opposed pair and a second opposed pair,(c) a broadhead blade of approximately triangular shape including a pair of forward razor edges intersecting at a point, and a trailing edge with a gap at the mid-point of said trailing edge,(d) a pair of extendable blades, each being generally L-shaped with a shorter leg, a longer leg, said longer leg including a razor edge along the edge corresponding to the outside of the L-shape, and a pivot hole near a distal end of the longer leg,(e) securing means for securing said broadhead blade to said body,(f) pivotal attachment means for pivotally attaching each said extendable blade to said body,(g) an elastic retaining ring,(h) said broadhead blade attached to said body by slidably disposing the trailing edge into said first opposed pair of troughs and securing it in position by said securing means,(i) each said extendable blade attached to said body by said pivot attachment means such that said extendable blades can pivot from a retracted position to an open position, and further orienting each said extendable blade such that in said retracted position said razor edge of said longer leg is disposed by itself within one of said troughs in said second opposed pair, and said shorter leg is toward said tip end and protruding out from said body, while in said open position said shorter leg is toward said shaft end, said razor edge is without said trough, and the distal end of said longer leg bears against said body and limits the pivotal travel of said extendable blade,(j) said elastic retaining ring secured around said body and said extendable blades to hold them in said retracted position until said hunting arrowhead strikes a target.
