Abstract: The invention relates to a dual-function citrus fruit chopper comprising a common base plate (1) which supports a guide device (2). Said guide device comprises an arm (2.1) which is provided with a rounded end (2.1.1) and an upper extending concave part (2.1.2) and which moves and presses the citrus fruit (3) against another corresponding part (2.2) until it reaches the position where it is to be cut down the centre (3.1). A cutting element (4) is disposed next to the guide device (2) and is used to cut the citrus fruit into semi-circles (3.2) of equal thickness except for the two ends of said piece of fruit.
