There is nothing magic to sharpening serrated edges!
1. IF they are just a bid dull, use a small stone like a fish hook stone. Use the EDGE, not one of the faces, of the stone and smooth out the curved facets on the serrated side. Now VERY LIGHTLY debur the non serrated side. You’re done.
2. IF they are really dull or burred, use the curved file in your jewelers file set. Pick the file that has about the same radius as the serrations. Reshape the curved facets on the serrated side. Now go back to step one and redo with the stone.
