Grooving plane comprised of three parts, a wooden rectangular body with an angled cutout through the middle and a metal portion along the sole to form the grooving profile (a), a wooden wedge piece that tapers to a point at the bottom and is rounded at the top (b), and an iron with a narrow blade (c). Stamped on the toe of the plane is "SHAPLEIGH DAY & Co. No. 119 N. MAIN ST. ST LOUIS MO", "75", and "I BLOWER". Stamped on the heel of the plane is "5/8" and "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.
