There is already an existing product of a screw driver handle with several bit heads sets. The handle can be attached to a crossed screw driver head, flat screw driver head, and other variations. My idea would apply the same concept that would apply for large tools such as shovel, axe, pick-axe, and garden fork. The handle would be designed in a way that it could be held the as for other tools such as shovel, axe, or garden fork. The handle can be easily connected to the tool heads. When storing the handle can be detached and placed somewhere else. While the tool heads can be stored separately. This idea also saves storage space.

There are several options such as this on the market.

I've seen screw on tool heads in the supermarket. Cool idea though, keep in mind Great minds think alike. Fools seldom differ. It's a paradox
