Abstract: A hand-held implement for controlled high pressure cutting or scoring. A grip constructed of relatively high density material and having depressions for the thumb, forefinger and middle finger is connected at its forward end to a cutting or scoring member, such as a carbide wheel for glass cutting. Extending rearward from the grip is an adjustable shaft having on its rearwardmost end a palm rest contoured to receive the portion of the palm between the knuckles of the forefinger and middle finger. The implement is gripped with the thumb and forefingers in their respective depressions and with the portion of the palm between the knuckles of the forefinger and middle finger seated on the palm rest. The side of the middle finger rests within its depression on the grip and the end of the middle finger contacts the surface to be cut or scored.
