These Block Planes has two cutter seats, where the cutter can be turned end for end to make the plane either work regular or bull nose. On the regular end of the plane is a knob, which threads directly upon a threaded boss that arises from the main casting. These are two rods that span the sides of the plane, which engage the typical lever cap with the large wheel underneath. Adjustment of the cutter is done manually. The cutter rests upon two triangular and fin-like projections that rise from the main casting. A very useful plane for regular works.
