A manually-operated, foodstuff slicer includes a top plate and bottom plate coupled together and housing a cutting blade within a recess formed between the plates. The top plate and bottom plate include spaced, circular holes defined therethrough and axially aligned, respectively, and the planar cutting blade having a handle and a plurality of circular holes which correspond in size and shape to the holes defined through the top and bottom plates. The blade is slidably retained between the top and bottom plates and movable along a plane similar to the plates.
