A wooden tonguing plane consisting of 3 parts.
a- The body is rectangular and made of a dark brown hardwood. A cheek protrudes from the bottom 2/3 of the front body. The throat cuts diagonally through the middle of the body and is exposed through the cheek. Th sole is flat with a straight groove running lengthwise down the centre. The back edge of the sole extends down to form a fence. Stamps on the toe read: "J.DRYBURGH/BRIGHT,ONT."; "I BLOWER". Stamps on the heel read: "I BLOWER"; "8/8"; "10".
b- The wedge is made of a hardwood similar to the body. It tapers to a blunt point on one end and is chamfered on the other with a rounded apex. An angular cut-out below the head allows for easy handling.
c- The iron is a narrow strip of grey metal. It abruptly widens near the cutting edge. The cutting edge consists of two chisel edges separated by a gap. The widths of the cuts are (l-r): 3/8"; 3/8"; gap 1/4".
Tonguing planes cut two parallel grooves in a workpiece. They are used in conjunction with a corresponding grooving plane to create tongue-and-groove joins. When used together, they are known as match planes. The iron of a tonguing plane contains two sharp edges and a central notch that leaves a raised ridge.
