The idea of the all-in-one hex key occurred when the designer start to think what is a more efficient and more aesthetic way to organize and to utilize hex keys. Hammers, drive bits, screw drivers, and ratchet handles; each one of them have its own function. Why a handful of hex keys must be together to perform one function? The re-designed hex key set can perform its function more easily and beautifully, saving lots of time and work.
