A novel and useful food chopper that includes a cutter having cutting edges arranged to form one or more cells and spring loaded plungers disposed and supported within the cells. The plungers include wipers extending around the circumference of the plungers at or near their bottoms. During a chopping cycle, the plungers are pushed back by the food to be chopped and compress their associated spring. When released, the wipers on each plunger squeegee the inner walls of the cell thereby achieving a cleaning action. Chopped food waste is minimized by careful placement of the wipers on the body of the plungers, placement of the plungers within the cells and by having a substantially flat bottom surface of the plungers which are mostly flush with the cutting edges of the cutter. Use of the wiper permits the food chopper to achieve very efficient chopping with minimal waste and a self-cleaning mechanism.
