Very thin E.A. Berg

[raven65536]

Hello,

I recently acquired this Erik Anton Berg. I am looking for some more information about it. The razor is very thin, 2mm, also at the spine and tang. I have never seen anything quite like it. The spine also has strange markings on the side.Too irregular to be ornaments, too regular to be damage of some sort.

I can't imagine it can be honed with such a small spine. Is there a piece of the razor missing? How would I go at trying to restore this one?

Thanks,
Luc
