There are many kinds of screwdriver heads and it is sometimes inconvenient to pick and change between the ones we need. Therefore, the team developed a screwdriver with easily changeable screw heads.
The Exchangeable Screwdriver is composed of five components – the magnetic cap, the slotted screwdriver, the crosshair screwdriver, the rocket screwdriver and the square screwdriver. They can be stacked to form an intact screwdriver. The user chooses the screwdriver head that is needed by changing the stacking order of the components before rotating to connect and secure the entire tool. The parts that are not needed then become the body of the screwdriver.
