ABSTRACT:
A method for producing a nondirectional pen includes the steps of drawing a solid metal rod 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; 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; welding a pen point ball to the tip of the pen body; slotting the pen body from its tip to a predetermined depth through the pen point ball to form longitudinal slots; and plastically deforming the pen body to close the slots.
