Abstract
Abstract A multipurpose tool useful in the construction of stained glass windows is described. The tool comprises a stiff, short blade having a curved cutting portion which sweeps around the end. The blade is provided with a short frusto-conically shaped handled which, in the preferred embodiment, comprises an inner core portion fabricated preferably of a heavy material and an outer sleeve portion fabricated preferably of wood, plastic or hard rubber. When used as a knife to cut lead came, the short construction of the present invention permits the end of the handle to be placed in the palm of the hand with the thumb and fingers placed generally parallel to the length of the handle along the sides of the handle as well as on the sides and back of the blade. This permits the entire strength of the arm, rather than merely the wrist, to be used for cutting the lead came, while permitting the hand to be still placed close to the lead channel being cut so that precise control over the tool can be maintained. The inner core portion of the handle is exposed at the end of the handle opposite to the blade so as to be useable for hammering nails into the work surface on which the stained glass window is being constructed. The end of the sleeve portion at the end of the handle opposite the blade is used for tapping on the edges of stained glass pieces in order to position them tightly within right came channels. Opposite the cutting end, the blade of the tool has a noncutting edge which is concave in shape, and which can be used to remove nails from the work surface upon which the stained glass window is being constructed by pivoting the tool about the cutting portion of the blade.
