Invented by Camcar Textron tools in 1967. ( Based on the British "Bristol " screw made in the 50's by Bristol Aircraft Co.)
The screws were invented first in the late 1700s and the handheld screwdriver first appeared after 1800.
The Phillips screwdriver was invented in Portland, Oregon in the eary 1930's by Henry F.Phillips.
The Strongest Screwdriver: Torx Pro.---In improving the standard Torx, they identified that it had sharp edges, which meant that the very tips of the "star" shape of the Torx screwdriver were ultra-thin (of course, since it comes to a point, like the top of a triangle.) So, Torx Pro made the edges of the star rounded, and it has become the strongest screwdriver made.---------Some of the strongest screw drive shapes -- in no particular order -- are:hexagonal socket (Allen)square socket (Roberts)"hexalobular" socket (Torx, TTAP)external hexagonalexternal squareSome particularly weak screw drive shapes are:flat slotted (?)cross (Phillips, Frearson)spanner head, dual pin (?)The weak shapes are all too easy to strip the screw head or damage the driver or both.Yes, but which one is the strongest? Well I'll give my vote to TORX (hexagonal star) or the somewhat similar TTAP
Albert Kohler of Prince George, British Columbia claims to have invented it
Apparently the first U. S. Patent for a ratchet screwdriver went to G. H. Talbot of Boston in 1858
It is a screwdriver with a 6 pointed bit invented and much used in the auto industry.

Torx screwdrivers are usually used in small electronics like computers and phones.
I assume this means: "Where can I find a torx screwdriver". Torx is a screw, with a hole looking like a six pointed star, or the star of David. You can find a Torx screwdriver in pretty much any hardware store, or well stocked super markets. They come in different sizes, so make sure you get the right size. They also come in the shape of Alan-keys, or hex-keys.
Your local auto parts store
A Torx screwdriver can be purchased through an online retailer or in store. Online retailers include Amazon, or IFixIt to name a few. In store retailers like Home Depot or Home Hardware would have a Torx screwdriver.
Rather than a screw or bolt head having a single slot to take a screwdriver, a torx screw head system uses a six-pointed star shape, and a screwdriver designed to fit.
You need a torx screwdriver....
