History of the Yankee Screwdriver,
The first spiral ratchet screwdrivers were produced in 1898 by North Brothers in the U.S.A. The name Yankee was soon adopted as a description of all spiral ratchet screwdrivers, although none managed to attain the same level of performance and quality of the original Yankee by Stanley, Yankee was truly the first cordless power tool and remains a very worthy competitor for workshop, building site, or production line.
