Multi-Bit screwdrivers are one of the best inventions of the modern era of tools. You get a well made screwdriver, usually with an ergonomic handle, and a number of bits stored conveniently in the handle. This gives you several tools while taking up only the space of one. If the bits break you won't need to replace the whole tool, just buy some new bits. Bit holding screwdrivers make excellent gifts and are great to have around just for the sake of convenience.
