Uberti SA hammer serrations

Hammer thumb serrations I know are stamped and I am asking what tool to use to sharpen them up...

A three corner file with one side ground smooth. I wouldn't get them too sharp at the tops but a clean bottom to the grooves makes them look better and gives a good grip.

Okay, I understand the reason for the smooth side, and I do have small 3 corner files with no smooth side.....but I was thinking of some kind of half round file small like a dime.......Thanks!
