ABSTRACT OF THE DISCLOSURE The present invention relates to the cutting, chipping and chopping of wood and, more particularly, to a machine using a knife-like blade for cutting and chipping wood into relatively large pieces in a direction transverse, or at least approximately transverse, to the orientation and direction of the grain. In accordance with the invention, the blade is oriented with regard to the angle of cutting to run between 70 and 30 degrees to the direction of fiber and grain. This oblique mode of cutting permits a lowering of the force requirement for advancing the blade by about two thirds of the force requirement inherent in vertical cutting devices. A cut carried out with a relatively oblique angle is preferably used for cutting wood having many knots, while a shallower angle of cutting will be used for hardwood grains.
