Sorry for the delay in getting back to this after you both took the time to answer my call for help. I only bought this to have a newbie bash at honing with some lapping film, (seriously uncool I know), but as a newbie I didn't ask if the spine was straight or for photos to decide for myself. It won't sit flat as it is. I think I might try your suggestion first Jamie and use a felt tip on the bevel to see if its making even contact. Failing that, a professionals point of view like Neil or Steve's is probably a wise course of action. Thanks for the input gents.
