I will have a look tonight to see if the spine lays flat against my honing stone..I probably should have looked at that before. The width of the bevel is very uneven. It kind of waves in and out and that is my main concern. The blades both have a very slight smile to them, more so at the heel than at the toe. I've only done anything with these two so far because these were the ones that had a slight chip in them and I don't want to ruin one that's in good shape already
