Edward D. Hill developed a husking tool called
principle of a twin wedge blade. Tool consisted of a stationary blade and a movable blade,
central portion of a cross bar, the ends of which slide on a spaced rod forming part of a frame.
and the other was a movable blade. It had a handle and a blade which can be separated from each other. The frame was
mounted on a support for increased stability. Coconut was placed in a bowl in the upright position and the blade attached
cross bar can moved in a vertical manner that helped to impale the blade on the coconut husk and separated the stationary
and movable blade causing husking. The unit operation can be repeated three or four times for complete husking. The
main problem associated with this tool was the difficulty to impale the coconut. Also it was strenuous to keep the
coconut on the bowl.
