A writing instrument is disclosed which includes a cartridge having a writing tip portion and a unique barrel having a generally elongated tubular configuration and an outer surface portion having a plurality of spiral shaped surface irregularities in the form of surface grooves which enhance the gripping of the barrel by the user. The barrel also includes a multisided inner opening which, combined with the outer grooved surface, provides a unique array of light transmission and diffusion which distorts the appearance of the cartridge and the barrel thus causing the barrel to have a translucent character. A method of producing barrel stock from which the barrels may be cut is also disclosed.
