Abstract
A device for starting a cutting wire through a material to be cut by the wire includes an elongated starter tube having an opening extending through its entire length. An insertion facilitating arrangement is formed at an insertion end of the elongated starter tube and a force receiving surface is positioned at the end of the starter tube opposite the insertion end. A handle is preferably connected to the starter tube at the end opposite the insertion end and the force receiving surface is preferably formed on the handle. By applying a sufficient force to the force receiving surface the insertion end of the elongated starter tube may pierce the material to be cut and be driven completely through the material to the opposite side. Once the starter tube traverses the material to be cut, one end of the thin and flexible cutting wire may be inserted through the tube opening until it too traverses the material to be cut. Then, while holding the cutting wire in its posiiton traversing the material, the starter tube may be withdrawn from the material leaving the cutting wire started and in position to be connected to suitable handles for manipulating the wire to cut the material.
