Nowadays the pencil-sharpeners pupils normal have can only help to sharpen pencils. While the waster collected will be thrown as rubbish. Not only pollute the environment but dirty the sharpener. Finally, the sharpener can no longer to be used. In order to solve this problem, we designed this new-style sharpener. "Gee·sharpeners" can depart sawdust and lead dropped from pencils . When it is full, press the sharpener , then the waster will be compressed into jigsaw puzzles. "Gee·sharpeners" contribute to recycle resource, as well as, it helps to develop kids' intelligence in a interesting way.
