A penetrating tip for surgical trocar is provided. The penetrating tip includes a generally transparent body having an opaque distal tip portion and an integral edge arranged at a distal end of the body. Inwardly tapered opposed facets are formed in the body, converging with one another at the integral edge. The opaque distal tip portion has a generally pyramidal shape. The inwardly tapered opposed facets are a pair of generally flat or planar first facets. The penetrating tip further comprises a pair of opposed second facets formed in the body intervening the pair of first facets and extending distally towards the integral edge.
