Rabbet and Rabbet Plane
A rabbet is a rectangular step or shoulder cut into the edge of a timber. This shoulder then provides a mechanical connection for joining other timbers. A better rabbet plane has a diago-nally set blade (a skewed iron) that draws the plane into this shoulder. The skewed iron also helps make a smooth shearing cut when working across the grain. The iron of a rabbet plane must protrude slightly from the side of the plane to allow it to cut evenly downward.
