I take it back It looked to me that it lost some belly due to too much sharpening. But I got one of mine out and looked closely, the blade shape appears to be very close to original. Enjoy! (polished or not)
I've cleaned up light scratching on blades like that using very fine wet&dry by putting the paper on the desk, near the edge and laying the blade flat on it then pushing and pulling to slide the blade lengthways. Using light pressure on the blade with the fingers of the other hand. If you just use the one patch on the paper it wears out as you go and effectively gets finer. I usually start with 800 or 1000 grit and find that it fixes most light scratches....
