Abstract
A finished workpiece of malleable metal containing a saw cut which does not require deburring because the small burr on the exit side of the cut is concealed within a three sided notch. An elongated notch, closed on three sides, is formed on the side of the blank workpiece from which the saw blade exits. The depth of the cut is adjusted so that the bottom of the cut, together with its attendant burr, intersects with the notch. The burr is thus attached to a wall within the notch. The width of the notch is adjusted so that the anticipated tolerance in the depth of the cut (and thus the location of the bottom of the cut) is accommodated. The width of the notch is such that the bottom of the cut will intersect the notch at any location within the anticipated tolerance envelope. The depth of the notch is sufficient to conceal the burr.
