A Brief History of the Screwdriver
The screwdriver is one of the tools that has been in use since the Middle Ages. Back in the 15th century, they were used for constructing screw-cutting lathes, securing breastplates, backplates, and helmets on medieval jousting armour. It was also used in the mechanism of medieval guns. These guns used pyrites which were needed to cause a spark for firing the guns. The pyrites were held securely using screws. The need to constantly replace the pyrites resulted in the necessity and the refinement of this tool. The earliest models had pear-shaped handles and were made for slotted screws. Over the course of time, the design of this useful tool has been developed based on its various uses.
Parts of a Screwdriver
All models have a handle, shank and the blade tip. They come in different variations depending on their usage.
The grip is usually made of metal, plastic, rubber, or wood. The handle is usually designed to exert maximum torque without your hand slipping. Plastic handles are commonly used because of their durability, but rubber grips are also added to provide comfort while using it.
The length of the metal that runs from the handle to the tip is the shank. It is usually made chrome, steel, or another metal and needs to withstand the force applied by your hand. The shank and the handle need to be connected strongly so that it doesn’t fall off even while applying high pressure on the handle. Some models even have shanks that reach the full length of the handle. This is useful when a hammer is used to strike the end of the handle.
The different types of blade tips commonly used are Philips head, Flat-head, Torx or Star, Hexagon, and Square or Robertson.
