When we use a set of screwdriver, sometimes we lose one of them or need more screwdrivers. To resolve these problems, we design a special tool which has four standards of screw driver. Furthermore you can handle it with just a hand. There are four slides switches. If you push one of them, a screw driver will come out at the top of product. It has three kinds of types and you can recognize a type as a figure located at the part of grip. We suggest three types(A phillips screwdriver, a flat-headed screwdriver, a hex key wrenches) follow frequency of use. With the Four in One, you can finish a work easily.
