Abstract
A material dispenser having a dispensing member configured to dispense a line of the material along a path in a downstream direction, and a cutting member having a cutting edge extending generally downstream with respect to the path. The cutting member having a convex shape across the path, such that the cutting edge engages and sequentially initiates cuts through the line of material when the line of material is pulled against the cutting member, thereby minimize cutting forces.
