This is an interesting little gadget, no matter how long you write or how fast you write The Uni-Ball Kuru Toga Mechical Pencil stays sharp. Â The days of using a pencil sharpener may be over. Thats if people still use pencils.
Because it has a twist and turn mechanism that automatically rotates its lead to keep a perfectly sharp point every time you write. Every time the writer lifts the pencil of a sheet of paper, the pencil sharpens itself. The lead never gets dull, brittle or weirdly thick or thin which will keep your writing or drawing consistent.  Check out the video of this incredible pencil.  Link:  The Uni-Ball Kuru Toga Mechical Pencil
