I have an old wedgie W&B Diamond Edge with a heavy smile that I've been restoring using Spyderco hones. My problem is I've been unable to make a lot of noticeable progress on it. I understand that the ceramics are real slow cutters and that wedgies are also slow work, but I've put days of work in and still no luck putting a trued-up edge on them. I've done the marker trick and all but the immediate heal are true. With other smiling pieces I've done I was able to catch hair off of the medium stones, but not with this one. Do I just need to keep going? Is it really THAT slow?
