Another option is a simple tool that makes it possible to shell maize several times faster than by hand. The device has the additional advantages of being robust, portable, transparent to users and only a fraction of the cost of other alternatives commonly on the market. The maize sheller is currently mass-produced using injection-molded plastic or cast aluminum. In regions where the device is not currently being manufactured or distributed, the tool cannot be locally made using these infrastructure-intensive processes. In response, the D-Lab program at MIT, in collaboration with their community partners, has developed several versions of the maize sheller that can be made using locally available materials and methods.
