Abstract

A writing instrument is provided including a gripping section arranged along a portion of the writing instrument normally used for gripping and a writing tip extending from the gripping section. The gripping section may be provided on a replaceable cartridge element which is inserted into a cartridge-receiving cavity in the writing instrument body. A soft, resiliently deformable gripping member is provided on the gripping section and is preferably tubular in shape. The gripping member includes a smooth surface which may include a slightly elevated or raised pattern. The elevated pattern may comprise a plurality of interconnected parts so as to form a continuous lattice or pattern such as hexagons. The pattern is preferably continuous over the entire smooth surface. The elevated pattern is resiliently compressible with respect to the smooth surface so that a user's fingers may deform the elevated pattern to provide additional traction during use.
