sharpener? no sharpener!!
The first impression it gives you is that it looks like a pencil sharpener, with a pivoted handle, the same shape both, but it isnt a wood-consuming and resources-wasting sharpener, by the opposite, it can produce pencil with abandoned paper.
That means the same move shaking hand to cut pencil brings environmental protection, not deeply rooted consumption in everyones common sense.
Thats it, the environmental protection living in the contrary thinking.
