In knife sharpening the forming of a feather edge is what it's all
about. I've done it many times by hand. So, I suggest you try using the
kinds of abrasives that would be used for knife sharpening. Start with a
course grit, and follow with increasingly finer grits. "Carborundum" should
work on stainless steel. Another thing to try is diamond (like a diamond
hone or diamond wheel).
Maybe these ideas will be useful. Good luck.
