1. A device comprising:
a shaft;
a distal member positioned at a distal end of the shaft, said distal member comprising:
a forward end and a rearward end;
a forward tip formed at the forward end of the distal member;
a right edge and a left edge progressing rearwardly from the forward tip,
the right edge and left edge defining a cavity therebetween and rearward of the forward tip;
a bottom defining a bottom surface, wherein the bottom is curved from the forward tip to the rearward end,
wherein the right edge and the left edge incline at an angle of between about 35 degrees to about 40 degrees relative to a linear axis extending tangentially to the bottom surface at the forward tip to form upwardly-sloping top surfaces;
wherein the forward tip is blunt;
wherein at least a portion of the cavity is U-shaped; and
wherein at least a portion of the right edge and the left edge are configured to cut tissue as the tissue advances in the rearward direction over the right and left edges.
