-18- STIFFENED CUTTING BLADE WITH REVERSIBLE/ REPLACEABLE EDGE MEMBER ABSTRACT A stiffened elongated cutting blade for use in a cutting apparatus of the type employing an elongated cantilevered cutting blade for cutting layups of fabric or other similar sheet material, and reciprocated along its longitudinal axis when actively cutting. The blade is a compound part made up of an inexpensive, reversible and replaceable edge member insert which provides the jutting edge and an associated holder supporting the insert for substantially its entire length along its rear edge and serving to reduce lateral and rearward deflec- tions. The insert is held in the holder by a mechanical interfit between the insert and holder at its lower end and in mechanical engagement with the holder at its upper end and is easily releasable from the holder to allow its reversibility and replacement after the cutting edge has dulled or worn beyond a desirable point.
