摘要： A method comprising grinding a lower knife-edge-joining portion (28a), a knife (42) apparatus for wood chipping, and a counterknife. A front side of the knife includes a recess and in the wood chipping machine the knife is clamped between an outer clamping (48) member adapted to receive the back side of the knife, and a inner clamping member (50) adapted (52) to receive the front side of the knife, the inner clamping member making contact with the front side of the knife at two spaced locations thereon (55, 57), wherein at least one of the locations (57) is outside the recess and the other is inside the recess (46), wherein the width of the recess (w) normalized by the overall width of the knife (W) yields a result that is preferably no more than about 0.22.

摘要： 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 (12) has an elongate axis (EA) and two spaced apart cutting edges (12a, 12b) parallel to the elongate axis and defining a first reference plane (A) . The knife is further defined by a plane of reflective symmetry (POS) 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 (28) projects from the front side and reaches a point (L) of greatest maximum projection of the knife from the first reference plane, the point lying in the plane of reflective symmetry.
