Abstract
A grooving tool has a support provided with a handle formed on its lower surface with a substantially flat sliding face and having a pair of generally parallel slots opening at this face and extending in a predetermined direction. A blade is secured in each of the two slots with portions of the blades extending beyond the face and the cutting edges of the blades forming a vertex in projection in the predetermined direction on a plane perpendicular to this direction. The parts of the support forming the lower surface can be displaceable relative to the blades to vary the spacing between the vertex and the surface for a different depth of cut. The tool can be drawn along a workpiece such as a board of insulating material so as to cut in it a very neat groove by excising a strip which may be of triangular section if the blades are planar or of semicircular section if the blades have curved lower ends.
