The Iketsetse single stroke maize sheller is a device used to separate the kernels from the cob faster than traditional methods and other crank type shellers. It consists of a leveraged plunger that pushes the ear of maize through a ring of spring teeth arranged so as to remove all the kernels from the cob with one motion.
