Abstract
A doctor blade is made from an elongated strip of reinforced composite material which material forms fibrillated protrusions when cut. A plurality of cuts are made in the material which form recesses or tabs. The recesses are offset to increase the effective thickness of the strip so that it can be inserted longitudinally or transversely into a doctor blade holder. The fibrillated protrusions maintain the recesses in an offset position.
