Abstract: A precision haircutting tool primarily designed to facilitate the cutting of one's own hair or someone else's hair easily and uniformly. The thumb of the hand used to hold the hair for cutting is slipped through the thumb ring and the finger guide (or stem) is allowed to extend between the index and 2nd fingers of the same hand. The hair is then combed upwards with the opposite hand and the hair is grasped between the same index and 2nd fingers between which the finger guide is being held. With the thumb resting on the head, the fingers are then slid up the stem to the finger stop and the protruding hair is cut above the fingers. By following a systematic pattern, the hair can be easily cut to the same length all over the head. By using various sizes of the device, a variety of hair lengths or combinations of hair lengths can be attained.
