A zipper is best classified as a type of mechanical fastener rather than fitting neatly into the categories of lever, pulley, ramp, screw, wheel, or wedge. However, it does function similarly to a wedge because the interlocking teeth of the zipper create a secure closure when pulled together. In essence, while it utilizes mechanical principles, a zipper is unique in its design and function.
