The grooves are oppositely inclined and the rollers are rotated in opposite directions in a frame a by toothed gearing driven by a hand crank e. A bracket c integral with the frame has pegs which pass through the holes or slot in the blade and into holes in the weight f. In operation, the edges of the blade vibrate slightly.
