“It seemed to me that almost all of your methods, from the sharpening process itself to the techniques for squaring a board, are based on very simple, intuitive geometrical arguments and it was a real pleasure to see the systematic way in which you built these arguments into methodical processes. These really work, and they take the mystery out of matters that are often treated as mysterious. However, they don’t take the satisfaction away.”
