I hate reccommending a dremel for gunsmith work, but if you have one you might consider picking up some of the small felt polishing wheels and some of that dremel polishing compound to smooth out that transition edge. It didn't take much, and you can't even really see or measure the difference. I would say it is akin to using a pocket knife to cut into sandpaper... you don't want to change the shape of the blade, just take the edge off.
