I've always used a small file to cut a notch.

Hi,
I am looking for a notcher that will cut keyway notches for a #6 rivnut
with a key. I have tried every tool store online that I can find. No one
seems to have them. I was outbid on a couple of used ones on Ebay and
haven't seen any since the last time. Any help would be appreciated.
