A flexible screwdriver is a type of screwdriver with a shaft that can be bent or twisted to allow the user to reach into tight spaces. This flexibility makes them ideal for use in situations where standard screwdrivers are too large or awkward to use. Flexible screwdrivers are also usually shorter than regular screwdrivers, making them easier to handle in tight spaces. In addition, many flexible screwdrivers have built-in bit holders that allow the user to easily switch between different screwdriver bits.
