1. In a sheet wrapping material dispenser of the type including a supply of elongated sheet wrapping material mounted on a support to permit a free end portion of the material to be grasped by a user, and to pay out a desired length of the material when the latter is manually withdrawn in a taut, generally planar, condition from the dispenser, a cutting element comprising:

  • (a) an elongated cutter body mounted on the dispenser; and

    (b) means on the body for sequentially piercing the taut withdrawn sheet material at a plurality of punctures spaced generally linearly apart from one another over the entire transverse width of the taut withdrawn material when the latter is guided thereover and relative movement in a single, smooth, manual stroke toward and into contact with each other is experienced between the taut withdrawn material and the cutter body, said sequential piercing means including a plurality of juxtaposed pointed coplanar teeth arranged lengthwise of the cutter body and having apices which are at different vertical elevations, said teeth having vertical axes at the top of which the apices are located, said vertical axes being parallel to one another, each tooth being symmetrical about its respective vertical axis, said apices being initial contact points for the material, whereby each puncture uniformly and symmetrically widens in transverse width and merges with adjacent punctures during the stroke to form a complete transverse generally linear cut.
