This is something I've wondered about for a long time and I'm finally getting around to asking the question. What is the point of a pyramid? It's been said many time, probably most assertively by Glen, that until you've set the edge, there's little point in moving on ot the next grade. If that's the case, why go from course, to less coure to least course and then back the the course stone again? Unless I'm missing or misinterpreting something (a distinct possibility), it seems self-defeating. Why not just go through one progression of the three stones?
