For a hand applied convex edge, the leather on wood system with polishing compound works very well. Some use mouse pads and various grits of sand paper with good results.
Yes, that is another good one not mentioned yet.
I have personally found mousepads to be a bit too spongy. I prefer something like the old military sleeping mats. They are a bit denser. Same concept though.
Whether it is stones, or hand convexing, the reason doing that is superior, IMO is field sharpening, or any other place that you are away from your "crutch." I have sharpened knives while on a long outing. You are sure not going to see anybody hauling an EZElap or edgepro out in the woods <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />
