The Sunkist Sectionizer was first developed in the 1940's. At the time, the only use for the sectionizer was to cut lemons into 6 or 8 equal sized wedges. Today your sectionizer makes quick work of wedging, slicing, coring or halving fruits and vegetables into uniform pieces and you now have a choice of 10 Blade sets that are all interchangeable. All of the Sunkist products are NSF approved, come with a 1-year warranty and are manufactured in the USA. For more information, visit our website at www.sunkistequipment.com
