The knob is decorated with the Kuru Toga logo and is attached to the eraser cap; 

you can press down on either to extend the lead. 

The rubber grip isn’t squishy so offer a more tactile feel.

Ingenious lead rotation mechanism that continually rotates the pencil lead as you write. 

A spring-loaded clutch twists the lead incrementally every time you lift the pencil from the paper. 

This allows a uniform wearing of the lead to create a conical tip shape that provides a fine, consistent line.

Standard Kuru Toga pencils rotate the lead once every 40 strokes

Features a sliding lead sleeve (guide pipe) that protects the lead as you write. 

As you write and the lead gets shorter, the sleeve slides into the pencil, getting shorter along with the lead. 

The sleeve can be fully retracted when the pencil is not being used, protecting it from getting bent or poking a hole in your pocket or pencil case
