Abstract
A writing instrument has a short tubular body which contains a writing implement on each end. A tubular, elastic finger retainer has a small plastic plate which is pivotally mounted to the body. The user of the writing instrument inserts the middle finger of his writing hand through the retainer and slides it to a position between the first and second knuckles. The axis of the body is parallel to the axis of the retainer during use. The thumb of the user pushes outward and downward against the body while the index finger is placed on an upper side of the body. The writing instrument may be pivoted to the other writing implement by applying a twisting force to the body.
