Solingen #14

[MikeB52]

Evening gents.
Took a chance on an ebay spanish site's offering of a #14 blade that looked similar to the 14's I've seen from Palmera, Filly etc.

Unmarked except for the #14, Solingen, and letters GH up at the pivot.
The horrible regrind along the bottom 1/4" to the edge was not apparent in the pics on ebay, and description was in spanish and when translated did not indicate it was reground either.
Seems a crime to do that as it was so thin to begin with. I have no idea what someone was thinking or trying to do to it.
Thinking I may try to just feather in the edge by hand with wet sand paper and hone it up.
Not one to complain on ebay and look for refunds on antiques normally. Byuer beware and all dat.
Ideas welcome regarding smoothing out the nasty step.
Cheers.
