Sonic Ratchetta Capsule Pencil Sharpener

With this ingenious pencil sharpener from Japanese Sonic, you no longer need to sharpen-release-grip-take-new-grip-sharpen-release… yeah, you get it. Namely, it has a locking mechanism similar to that found on a ratchetta screwdriver. That means it's enough just to spin the pen back and forth.

This pencil sharpener has two modes: one to achieve a sharp/thin tip, while the other one achieves a broader tip. The latter is especially useful when it comes to colored pencils.

The container also collects the flakes when sharpening.
