In fact by the end of the playoffs they all had it and I had come to find out they use a Triple Profile on all Players were the Penquins use only the double. There was some very interesting things there. Penguins (hardly anyone on Step and double profile) Redwings (all on Step and triple profiles) Triple profiles - is that different radii for the front, mid, and back of the blade? And, is it blended in by eye, or are there triple profile template bars? also what are the benefits of a triple profile?
