A grooving plane comprised of three parts, a wooden rectangular body with an angled cutout and a metal portion fixed to the front to aid cutting the groove (a), a wooden wedge that tapers to a point at the bottom and has a rounded top (b), and an iron with an angled blade that is the same width as the groove profile on the plane's sole (c). The wedge and the iron fit together inside of the plane's body, and the wedge holds the iron in place as it cuts. Stamped on the plane's toe is "I BLOWER", and "WALLACE". Stamped on the heel is "I BLOWER".
Grooving planes are used to cut straight grooves, or rabbets, into a working piece. They are traditionally used for drawer bottoms or rear walls. They can be used in conjunction with a corresponding tonguing plane, which creates two parallel slits in a piece of wood. These create two pieces that fit together perfectly for joining work. Other names include dado planes, ploughing planes and matching planes when combined with a tonguing plane.
