<p>An elongated blade has a notch in its leading edge, with parallel chisel edges adapted to chop through the oriented fibers (boron or graphite) of uncured sheet material as the blade is reciprocated vertically at a high frequency relative to its forward velocity (five cycles per blade width). The notch is about half as deep as the blade width and has a vertical extent (between the chisel edges) of about 60 percent of the blade's vertical stroke. The blade has a lower edge which forms a 135 degree angle with it's leading edge, and which lower edge is spaced below the lower notch chisel edge by approximately the width of the blade.</p>
