ABSTRACT:
A food wrap cutter includes a base body disposed under a slot on the front wall of a main body, a guiding element with elastic moving function disposed on the base body, and a guiding wedge of the two guiding elements coupled to a cam slot at a lower panel. Thus, when the guiding element is pressed, the lower panel is lifted by the action of the guiding element on the cam groove such that the upper edge of the lower panel is higher than the upper edge of the cutter; and the guiding element drives the upper panel to lift and separate the upper and lower panels in order to protect a user's hand from being cut or scratched while pulling out the food wrap.
