Not every home has a large set of tools, but everyone has a couple of screwdrivers that can be used for various jobs. The length of the rods is extremely diverse, depending on the purpose - so, there are short screwdrivers, for "local" use, and there are very long screwdrivers, which have a rod much longer than the handle. Such screwdrivers are convenient to work in hard-to-reach places. This is exactly the kind of screwdriver every owner should have in his arsenal.
