I would like to know the secret with diamond stones. Plenty swear by them, but I do not have the touch with the two I have tried to use. I heard that you have to put some wear on them for them to work best, but I have past that point and still struggle with the diamonds.

FWIW
I have an EZE LAP model "M" that I would like to sell. It is a two part sharpener with a sheath. Diamond rod can be screwed into the handle for storage or in a fixed exposed position for use.
I bought two when a customer wanted one incorporated into his knife sheath. Have not used the one I kept.
