Abstract: A method for producing a nondirectional pen includes the steps of drawing a metal pipe to form a pen blank having three or more radial blade sections extending along the length of the pen blank and equally spaced angularly away from one another, each of the radial blade sections including an internal gap extending along the length of that blade section; cutting the pen blank into pen bodies having a predetermined length; shaping the forward end of each of the pen bodies into a substantially conical configuration; slotting the pen body from its tip to form longitudinal slots each aligning with the internal gap of the corresponding radial blade section; and providing a hard pen point capable of writing.

Abstract: A socket for holding the writing ball of a ball point pen comprising an outer tubular member having a circular cross section and an inner tubular member having an elliptic or circular cross section, wherein an ink-conducting chamber or chambers are defined between the inner peripheral wall of the outer tubular member and the outer peripheral wall of the inner tubular member, thereby enabling ink to be conducted smoothly from an ink cartridge provided in the ball point pen through the chambers to the writing ball.
