A cutting tool has cutting teeth attached to a base surface of the cutting tool. Each tooth is provided with a generally vertical leading face that is arranged at an angle relative to a forward stroke direction of the cutting tool, and a corresponding, similarly shaped trailing face relative to said forward stroke direction. Extending between the leading face and the trailing face is at least one cutting surface perpendicular to the leading face. The cutting surface has an elongated, generally linear crest having a length that extends between the leading and trailing faces and is situated at a distance from the base surface. Each leading face forms a piercing corner with the crest. The teeth of the cutting tool are arranged in a plurality of rows, with each row being oriented generally perpendicularly to the forward stroke direction. Each leading face of each tooth of at least one row is oriented at an angle relative to the forward stroke direction.
