Thanks for the advice Gugi!
I used an old printers loupe (I used to be in the printing biz) to examine the edge. One of the old junkers I have has a bevel that's not very even. The spine isn't even either. Think that one might be a goner, unless I had someone re-grind it maybe?
The other one I honed started out in good shape. Nice even bevel across the entire blade. I'm hoping for a better result from that one.
