Should we consider a tool such as this traditional?
I doubt it. I have only ever found references to one way of sharpening flints, and that's what the old boys called hammering. I've never really figured it out, but in some way the flint is forced against the heel of the frizzen to flake the edge. No tool is used.
An item is very frequently offered for sale or mentioned in other ways in the 18th century, called a 'gun hammer'. It's not the cock, but some sort of accessory tool. Maybe it's one of those combination tools with a knapping hammer?

"Just imported from London, in the Carolina, James Friend, Master, and to be sold by THOMAS SAVADGE.... steel pinchers and plyers, nutcracks and
gun worms, chargers and hammers, and sundry other sorts of steel toys,"
However you do it, unloaded guns only, if you are going to knap the flint while in the jaws.

Annapolis, in Maryland February 7.
"Some days ago, as a man in Talbot county was hammering the flint of a loaded gun, she went off, and shot an elderly man, who was near him, in one of his thighs, with seven swan shot, in a terrible manner; tho' it was thought he would recover."
