The Screwdriver's Backstory
Screws are sometimes referred to as "industrial rice" and require a screwdriver to spin.

Prior to the first industrial revolution, the brothers Jobg and William Wyatt discovered a low-cost method of producing screws on a new kind of machine, which resulted in the widespread use of screwdrivers and screws in general. The increasing use of screws in industrial settings has resulted in the advancement and variety of screwdriver technology. was born in Seneca, Ontario, Canada, in the year 1879. After being hurt while using a straight slot screwdriver, P.L. Robertson (Robertson) discovered that when a slot screwdriver's torque increased, it became slightly easier for people to slip and get hurt. This discovery directly led to the creation of Robertson's technique for reducing slippage when screwing.

This immediately gave Robertson the notion to create the square slot screwdriver by figuring out how to reduce slip when screwing in order to enhance torque.

Because of the self-centering characteristics of the Phillips screw design, which significantly aided in the popularization of automated manufacturing lines employing electric screwdrivers, Phillips was given the best chance to truly popularize the screw. Despite its simplicity, the screwdriver was revolutionary and, more than any other hand tool, it embodied the spirit of the Industrial Revolution. How do the components of a machine work together as a whole? The screwdriver inserts millions of screws into the machine, and "industrial rice" is the most essential item!
