The ratchet screwdriver does not have one clearly agreed inventor, because several early ratcheting screwdriver patents appeared in the 1800s. One of the earliest listed patents was by G. H. Talbot in 1858 for a ratchet movement for screwdrivers. Later, German toolmaker Conrad Baumann became known for the Baumann Weltrecord ratchet screwdriver, an early and famous ratcheting design. EnrgTech offers ratchet screwdrivers for faster screwdriving, repair, and maintenance tasks.
