A wood chip screening system has an infeed end, outfeed end and elongated thin blades (40, 42) mounted for reciprocating motion extending therebetween. The blades (40, 42) are spaced apart to allow chips with an acceptable thickness dimension to pass therethrough. The improvement includes configuring the top edges of the blades (40, 42) in a nonlinear design.
