Gesswein EDM Blue All-Grit Set - 6 Piece

These stones are the best. I found the orange ones a little fast wearing for my application, and the blues seem to really stay flat so far. I try no to have to use the 120-180 grits, but 220 up has been perfect. Gesswein is awesome, and the packaging for the stones has been great, I've ordered 3 sets so far, and won't hesitate to order more.

Like these for getting knife shaped up
