REPROPLAST Onion slicing holder

Insert the holder across the halved onion and pass the knife between the needles. We turn the holder and cut small cubes. We do not cut close to the needles, we turn and cut from the other side. Ideally, you can also cut tomatoes or mushrooms into slices better than with the sharpest grater. We can also use the holder to remove fish scales. You insert the holder against the cutting board into the tail fin, so the fish does not slip and you can easily scrape off the scales.
