ABSTRACT:
An improvement to a writing instrument with stylus, a pocket clip and an integrated letter-opening blade. The improvement consists of locating the letter-opening blade in the pocket clip of the pen. The blade is prevented from cutting the pocket of the user due to a blade protector that is mechanically linked to the mechanism that extends and retracts with the marking or writing tip. In an alternate embodiment, the blade is located on the opposite side of the pocket clip. The extending and retracting mechanism can be a variety of types including twist, press, sliding. The stylus provides input to a PDA, touch screen or other tactile input device. Another embodiment includes a letter opener with a stylus.
