Five different pencil sharpening modes are available and can be used with two different pencil thicknesses.
If the pencil tip is broken in the wooden holder (e.g. when dropping the pencil), other sharpeners often get the broken piece stuck, but the dingb's anti-jamming system easily solves this! All you have to do is press the adjustment button on the rewind lever and the jam is cleared. The same button also allows you to easily adjust the shape and fineness of the tip.
