ABSTRACT OF THE DISCLOSURE A hand-held implement for controlled high pressure cutting. 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 member, such as a carbide wheel for glass cutting. Extending rearward from the grip is an adjustable shaft having on its rearward- most 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. The implement allows controlled movement of the cutting member for making curved cuts in glass and allows generally equal forces to be applied by the fingers and the palm, thereby increasing the amount of force which can be applied and minimizing hand fatigue.
