So I picked up a Geneva Cutlery razor from an antique shop a couple months back and what originally caught my eye was the beautiful smile and great condition of the razor...even though one scale was missing on the tang end of the pivot pin. I bought it and after smiling over it for awhile...I noticed that the smile wasn't square. It was definitely honed by someone who was inept at the rolling X. As a result, the toe end of the blade is narrower than the heel.

What is a relatively easy way to straighten the smile without taking too much off the blade? It's a little narrower than I usually go for (5/8 on the heel, closer to 4/8 at the toe).

Thanks for the input, Gents.
