woodsaving sharpener / Pencil sharpener

Wood is the main material of the pencils. The “wood-saver” sharpener can save woods by changing the shape of the head of the pencils. The wood we save from one pencil is not so much, but if every one of us uses this sharpener, the effect will be obvious. There will be a lot of trees to be saved every year.
It’s not very different from the common sharpener. The only change we have done is on the cylindrical blade which makes it easy to accomplish the design.
After you insert the pencil, rotate the handle of the sharpener with one hand.
