I think I have located the problem. It appears that the spine has been taped. Maybe even double taped or with thick tape. I looked at it under magnification and there is a very slight double bevel.

In mountain biking momentum is your friend in honing magnification is your friend. :) I never even start without taking a looksee at the edge.
I sometimes do that but I have cataracts so it is hard to see really fine detail. I used to be a jeweler so I put on an optivisor and looked through that and a magnafing lamp to see it. I will start over with a diamond stone. Thank you all for your help. You guys are great and I well never take offense at suggestions. Mack
