         priate for cutting wire. The blade portion 302b is coupled to
         the attachment structure 316. In one example embodiment,
         the blade portion 302 is hingedly connected to the attach-
         ment structure 316 via a hinge screw 306a inserted through
         a hinge opening 306b of the blade portion and coupled to the
         attachment portion 316. In another example embodiment,
         the cutting device 302 interacts with a spring 326 that pro-
         vides resistance when pressing down on the cutting device.
         The spring 326 is coupled to at least one of the attachment
         portion 316, or an upper face 408a of a support member 408
         of the dispensing apparatus 400 (see figure 5).
           In one example embodiment, the attachment portion 316
         comprises an upper area 328a and a lower area 328b. The
         attachment portion 316 comprises one of metal, plastic, or a
         combination thereof. In another example embodiment, the   Figure  5: Perspective view of a cutting apparatus and dispensing

                                                              example embodiment, the middle portion 318c is threaded
                                                              through the connecting opening 310a and attached to the
