Abstract
A wood chipper knife includes a knife body and, in relation to a vertical axis of the wood chipper knife, at least one cutter side, which comprises a top cutting edge portion and a bottom cutting edge portion that intersect to form a cutting edge. The bottom cutting edge portion includes a planar wood attacking portion, which begins at the cutting edge and towards the knife body is followed by a recess. The recess is a pressure release recess, which, from the wood attacking portion, abruptly falls to a bottom of the pressure release recess, and which stretches from the wood attacking portion to the knife body. The knife body comprises a chip guiding portion, which, from the pressure release recess, rises towards the knife body.
