First One Handed Folder

[Thrustus]

What was the first manually operated one handed folder on the market? Stud, hole or disc opening. The earliest models I can think of are the Spyderco Police, SOG Tomcat and Blackjack Folding Mamba.

If you want to count the Butterfly knife, research puts that to pre-1800's(lot of argument on when and where they were created).

I just got one of those "Higo knives" a design from the 1800s
