It's a drag saw. If the striations are straight it might be like the saw used in the experiments of Stock (2001). If the striations are curved might have been attached to a pendulum rig of some kind (one posible one is discribed in Moores (1991)). If the cut is straight and narrow the blade was flat and held in place by a jig along with the block.
