ABSTRACT:
A barrel for a ball-point pen is formed with three concave surfaces extending along the length thereof. Such a construction facilitates the firm holding of the pen barrel in an untiring manner by the thumb, forefinger and middle finger of the hand of the user. To reduce the cost of the manufacture of the pen, the ink is contained in a hole extending through the longitudinal center of the barrel.
