If you check the honing section in the Library, you'll find it refers to the "theory" behind the Pyramid method of honing, then goes on to discuss practice instead of theory. Whatever the theory may be, Pyramid honing is helpful for people who are beginning to hone and have no set method for doing it. I've tried it, and it works, but I much prefer going through natural stone progressions because I have learned through practice when the time to transition from stone to stone has come. For those who lack experience, the Pyramid method is a place to start.
