Dr. Grip
From Wikipedia, the free encyclopedia
Dr. Grip is a popular brand of mechanical pencil made by Pilot Pens based in Japan. Dr. Grip's also come in a pen variety. It is well known for its "deflection-deflection/knock system"
The deflection-deflection system is a special form of lead advancement. A pencil using this system is also commonly known as a "shaky pencil". A small, metal weight lies around the core of the pencil, and when shaken, slides up and down; thus pushing the lead advancer down and advancing more lead.
