A pair of saw blades includes a first blade, which is adapted to rotate in a first direction about an axis of rotation, and a second blade, which is adapted to rotate in a second direction opposite to said first direction about the same axis of rotation. Each blade has a blade body and cutting elements, which are provided along the periphery of the blade body and adapted to run close and in parallel to each other when the blades are rotating. A spacer, which extends into a space between the two blades, is attached to at least the blade body of one of the blades in order to support itself against and slide along a peripheral part of the other opposite blade.
