Nosing molding plane comprised of five parts, a rectangular body with a round groove on the sole (a), a wooden wedge that tapers to a point at the bottom and is rounded at the top (b), an iron with a curved blade (c), a second wedge with a tapered bottom and a rounded top (d), and a second iron with a curved blade (e). The wedges and the irons fit together in two sets inside of two angled cutouts going through the body piece, and the wedge holds the iron in place as the plane runs across the wood surface below. Stamped on the toe of the plane is "DRYBURGH N.E. HOPE ONT." and "I BLOWER". Stamped on the heel of the plane is "I BLOWER", and "1 1/4".
Nosing planes were primarily used to round the front edge of a stair tread, although they were used for other rounding tasks as well. Most of the later nosing planes had two irons. The difference between a Hollow and a Nosing Plane is the that the Hollow is a very shallow cut while the Nosing Plane cuts almost a full 180 degrees.
