Dr. Grip

Dr. Grip is a brand of mechanical pencil made by Pilot Pens based in Japan. The Dr. Grip style also comes in a pen variety. It is well known for its "deflection-deflection/knock system." For its ergonomic features, the Dr. Grip pencil has been awarded the Arthritis Foundation's "Commendation for Ease-of-Use."

Features

The deflection-deflection system is a special form of lead advancement. A pencil using this system is also commonly known as a "shaker 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.

For ergonomics, the Dr. Grip pencil was designed with a wide barrel and cushioned grip to relieve writing stress and fatigue.

Models

The majority of Dr. Grip pencil models only differ in color. The "Center of Gravity" pencil is a slightly different model in that it's designed with a different weight distribution for more comfortable, balanced writing. It's also has a wide double layer comfort grip to reduce writing stress. In the United States this pencil comes in a model using 0.7mm lead only. In Japan the G-Spec Dr. Grip is available, which is the same pencil, but using 0.5mm lead.

The pencils are available in 0.5mm and 0.7mm depending on the style of pencil.
