Screwdrivers are very well known, common domestic tools. Every home has at least one screwdriver within, as there are so many items that require the use of screws. They are not just used for domestic purposes but are used in professional manufacturing too. Screwdrivers are usually manually operated and are made to carefully match the screws that they drive. This is determined by the shape of the hole in the screw’s head where screwdriver’s tip fits into it. There are also automatic screwdrivers that don’t require the user to drive screws by hand. Basically screwdrivers consist of four parts: 1) the tip, 2) the blade, 3) the shank, and, 4) the handle.
The quality of a screwdriver is judged by the blade and what kind of metal it is made up of, how its finishing is and the efficiency of the tip of the screwdriver. If the material and quality of the blade is poor then it may start chipping when you start exerting pressure on it; it may also crumble under extreme conditions. It is necessary that the blade is properly and firmly attached to the handle of the screwdriver so that the blade doesn’t fall out of its handle, and so that it doesn’t get loose or slip inside the handle of the screwdriver. The material of the screwdriver is also important so that it provides better grip to its user.
