When a pencil is sharpened down to one-third of its original size, it becomes difficult to hold. These pencil stubs are typically discarded. The Eco-Friendly Pencil Sharpener has three features that allow pencil stubs to be reused — a conventional pencil sharpener, an internal thread cutter and an external thread cutter.
The Eco-Friendly Pencil Sharpener was inspired by the screws used in everyday life. The sharpener mechanically shapes the pencil stub into a threaded shape, then shapes the end of another pencil into a nut, allowing both pencils to be joined. The two parts combine to form a whole pencil, and hence, they do not need to be discarded.
This sharpener is sleek and curved, making it comfortable to hold and use. The symbols at each end provide quick identification. There is finally a convenient way to extend the lifespan of pencils while conserving natural resources.
