Abstract

An apparatus for cutting wood into small pieces, such as logs into pieces of firewood, and comprising a rotatably mounted knife means (1) with a helicoidal blade (4, 5), the cutting edge (8, 9) of which is helical. A support means associated with the knife means (1) and supports the material to be cut. The cutting edge (8, 9) is situated on the edge (10, 11) of the blade (4, 5) facing the axis of rotation (2) of the knife means (1), and the the distance between the cutting edge (8, 9) and the axis of rotation (2) of the knife means (1) decreases towards the feeding direction (12) of the wood.
