    Abstract: Device for use in connection with wood chippers of the type comprising a rotary disc (15) whereof one face is fitted with substantially radially positioned knives (1) which are attached thereto by means of knife holders (2) incorporating a log guiding surface. To give a twisted form to one face of the knife holders (2) the latter are fabricated by surface grinding of the log guiding face while the knife holder (2) is clamped in a grinding fixture (20) in a state of torsion which, after removal from the grinding fixture, gives the desired twisted shape to the log guiding face. After removal from the grinding fixture (20) the knife holder (2) is clamped in a torsion-free state in the chipping disc (15).
