Dear Fellow Razorheads-Just received my Norton 3 stone set and was wondering how long to soak the stone before usage. I have heard everything from 15 minutes to 2 weeks. If soaked too long, the stones can separate where they're glued, correct? FWIW, I also have a DMT 325 flattening stone en route,along with a $14.00 Nagura stone that I bought at Woodcraft. Again, thank you for any specific information-Gearhead
