A guy at my work brought some knifes in to be sharpened. Two of them are straight blades, and came back like they were sharpened with a bench grinder out of a welding shop. The 3rd is a fairly expensive ($300) serrated blade. Looks like they did the same thing sharpening as they did the straight blades. He's pretty P.O.'d about it, and is wondering if the blade is shot, or if it can be salvaged. I used a camera phone, can try to get better pictures.
