Thumb mountable cutting tool includes a sleeve which receives a thumb of the user and a blade is secured to and extends longitudinally along the sleeve. The tool is placed on the user's thumb, with the blade extending away from the hand, or along the outside portion of the thumb or the top portion of the thumb, and is accordingly in position for cutting tape by a cutting motion of the hand or the thumb. The blade is preferably a serrated blade to facilitate cutting tape and at the same time to prevent possible injuries which may occur if the blade were smooth and continuous. The serrated edge readily cuts all kinds of tape, including tape with fibers embedded therein. For cutting boxes, the tool may be removed from the thumb and held in the hand for additional leverage and ease of cutting in different directions as may be required in opening boxes.
