Screwdriver / Pencil sharpener & Eraser

In this product, screws and nuts represent the combination relationship
of parts and components.

We use the relationship of the moving of screws and nuts, make
the action of sharpening pencils as rotating the six-angle screws.
And save the energy when sharpening pencils through the rotating
of screws. In rotating between locking and sharpening, pencils will
be sharpened by the clever conversion.

And the funny six-angle nuts are erasers that can be combined and
added. We use the shape of the corners to make it easily when
erasing. And the erasers can be added and stored with the main
body, the screws-pencil sharpener.
