- a blade body having a front surface, a top surface, a bottom surface, a first side edge and a second side edge;
- said blade body having at least one mounting aperture;
- and
- each of said first and second side edges having an irregular configuration such that adjacent segments tightly and nestingly engage each other along complementary side edges as the adjacent blade segments are mounted upon a railway regulator wing,
