Youll have to try to picture this. I use a lansky and know exactly what you mean. What I did to solve it was get longer screws for it Then you can open the jaws at the guage hole end. And slightly close the jaws at the clamp end. Thus fitting any full flat grind perfectly. I got one to fit my CG ASH1 exactly. It will take a little adjusting to get it just right, so apply some blue painters tape to the spine to avoid scratches.----Robert
