I'd take a bit off the heel, as I think that'll be an issue; and of course remove the frown. I think it'd take quite a bit of work and you'd need to remove a fair amount of metal but if it was me I'd be tempted to give it a go.

In one of the photos it look like it has a really really wide bevel near the toe, but it just may be the picture. It doesn't seem to have a lot of spine wear to me.

I'd give it a go honing it for nothing; but you'd need to pay the postage to me. I'd post it back, as I'd like the opportunity to have a challenge and also have one of my edges evaluated.

It might be worth getting new scales too, even though it looks like they're hanging together.
