Abstract
A knife assembly and chipping knife therefor. The knife assembly includes a knife, and employs an upper clamping member and a lower clamping member for clamping the knife therebetween. The knife has an elongate axis and two spaced apart cutting edges parallel to the elongate axis and defining a first reference plane. The knife is further defined by a plane of reflective symmetry that is perpendicular to the first reference plane and which contains the elongate axis. The knife has a front side and a back side spaced from the front side. The front and back sides terminate in the cutting edges. A deflector ridge projects from the front side and reaches a point of greatest maximum projection of the knife from the first reference plane, the point lying in the plane of reflective symmetry.
