Abstract: A fishing spear tip for mounting on a fishing spear shaft has a first, second, and third spear prong mounted in a prong holder having a central longitudinally extending straight bore extending rearwardly from the forward end thereof and adapted to receive the proximal end portions of the first, second, and third prongs therein. An adapter is operatively associated with the prong holder for attaching the prong holder to a spear shaft. Matrix material is positioned in the straight bore in the prong holder in fixed bonding relationship therewith and in fixedly holding, engaging contact with proximal end portions of the first, second, and third prongs. The central longitudinal axes of the first, second, and third prongs, and the central longitudinal axis of the prong holder all are positioned in nonparallel, nonintersecting relationship.
