My mother recently sent her heirloom cleaver to a local sharpener and it returned with two beveled edges
. When he returned the next week, she pointed out the problem, and asked if he could fix it. She knew that a significant amount of grinding would have to be done and was prepared for a blade that was somewhat less wide. When the knife was returned the second time, it was evident that the sharpener had used a belt sander on the surface of the blade, and had not only taken off about 1/4" of the curve, but changed the shape so there is no longer that wide, satisfying rectangle that separates you from what you're cutting. There is discoloration on both sides and some small black patches on the bevel that look like they are eating it away. Also, it rusts quickly, despite oiling. I can just see the sparks flying. The poor knife is painful to look at but my mother still uses it. Is there any hope of restoring the surface or is this knife damaged beyond repair?
