Abstract
A spear structure is defined by an elongate truncated conical body formed with a forward section and rear section intercommunicated by a frangible hollow sleeve arranged for separating the forward section relative to the rear section upon impact. A spring member directed through the sleeve and secured at its upper and lower distal ends to the forward and rear sections secures the forward and rear sections together upon such separation to preserve the rear section for reuse.
