Do you think this is repairable? Degree of difficulty? I am mostly concerned about the edge and etching

Yes, Maybe.

Depends, what tools do you have and what is your level of honing experience?

Not especially difficult and no extra ordinary tools needed.

Diamond plate, pair of calipers, 1k, 4k and 8k stone, good magnification and a sharpie.

The Etch should be unaffected.

Reshape the edge, to match the spine and even out the toe. Once you level the edge in a spine matching smile, set the bevel and see if it will hold a chip free edge.

If you just set a bevel, you will have to remove a lot of metal to get to good steel, so remove the metal and the chips first and reshape the edge at the same time, then see if the steel is any good. It will only take a few minutes to properly reshape the edge.

Good news is it is not a particularly rare or pricy razor, and it is pretty trashed, a good candidate to learn on.

Here is a post on reshaping an edge step by step, (Make me Smile).
