This sheller is a simple device meant to save time and energy in meal preparation. Most families remove the corn kernels by flicking off each individual kernel by hand. With the sheller, the corn cob is inserted into the hole and the sheller is cranked around the cob until half of the cob is cleaned. Then, the cob is turned around and cleaned from the other side.
    The sheller can easily be made by local carpenters. Actually, it can be made by anyone with a saw and a drill. Above is the general shape of the instrument. The handle needs only to be long enough to fit your hand around. The head needs only to be thick enough to ensure that it is strong and won't immediately break in use. The central hole in the head needs to be the size of a naked corn cob, or about 30 mm. The four holes on the perifery need to be about the size of corn kernels.
