A document shredding machine comprises cutting mechanism comprising two shafts, each mounted for rotation about a respective parallel axis, and cutting discs mounted at spaced intervals on each shaft, the two sets of cuttings discs intermeshing and the shafts being rotated in opposite directions so as to provide a downwardly-accessible nip into which documentary material (such as paper) is fed. Engagement between the circumferential edges of adjacent discs subjects the documentary material to a plurality of longitudinal cuts, and the discs are provided with transverse cutting edges by which the material is subjected to a transverse severing.
