What it is
A set with five handles and ten sockets that snap onto them, so one person can carry an assortment of wrenches in many sizes. It was sold under the Snap-on brand from 1920 and revolutionised the automobile workshop.
The ratchet socket wrench is credited to J. J. Richardson (1863) in some sources; Snap-on popularised the interchangeable handle-and-socket system in 1920.
