Another ingenious invention from Japan. You probably have been through this before: jotting down something in a hurry the lead on your mechanical pencil point breaks forcing you to stop to push out more lead. These mechanical pencils count with a mechanism that protects the graphite lead against excessive pressure from the user. When extreme force is applied the metal feeder on the pencil comes out to protect the graphite lead and avoid breakage receding once the pressure stops.
