what's so bad about a flattened spine anyway? is it just aesthetic? or does it cause some problem in stropping/honing/bevel setting? and what is a "worked out bevel"? thanks.
+1 on that. I am aware of the problems which could be caused by a pit or rusting edge, chips, and cracks alike, but I wasn't sure what problem a flatten spine posed, or what a worked out bevel was.
