Now I recall those posts over the years, and that I looked everyplace for a Wyatt, I think it was Peterson in "The American Sword" that mentioned Wyatt (Joseph) was a silversmith in Philadelphia. As often the case, these guys often acted as cutlers and used various components in assembling swords as required. As British subjects they of course in various cases supplied the British regiments posted abroad in the colonies.
There were a number of apparently more prolific makers such as Potter, Rose, Pettibone. As far as who used the swords made by these men, not sure how that material would be discovered especially as obviously there were reasons for not keeping such records with disparity in sides taken.
Knowing which units might have used the swords by specific makers would take a good deal of study of the history of the Revolution and the units engaging in certain events and campaigns. Sourcing to Philadelphia simply relates to the information suggesting Wyatt being located there, where his swords went and to whom would be difficult to determine, but like everything, who knows what information lurks out there!
