So i have a 1000/220 grit hone, nothing special i got it from wipped dog.com After reestablishing my razors edge and give a few knifes there life back, i notice that the edges are worn down. I looked up this on the internet and saw these stone flateners and i thought you know i paid 8 dollors for this if i break it, so what. So i went to my basement and grabbed some sand paper, and started doing to work at the stone. But then i realized that i have an old style belt sander. After setten the stone on a flat surface, i just went to town on the stone. and it seems to have worked, i am not sure if this is wise to do on like a new Norton stone but if you don't really care about the possible break in a stone this could world well. http://straightrazorpalace.com/images/icons/icon7.png
