1. A penetrating tip for a surgical trocar, the penetrating tip comprising:

  • (a) a generally transparent body having opposed proximal and distal ends, the body including an opaque distal tip portion having a generally pyramidal shape configured to ease penetration through tissue, wherein the opacity of the distal tip portion helps to reduce internal reflections within the tip;

    (b) an integral dissecting edge arranged at the distal end of the body;

    (c) a pair of inwardly tapered opposed planar facets formed in the body, converging with one another at the integral dissecting edge; and

    (d) a pair of opposed curved facets formed in the body, separating the pair of inwardly tapered opposed planar facets from one another and extending distally toward the integral dissecting edge.
