From Wikipedia: "A sickle is a hand-held agricultural tool with a curved blade typically used for harvesting grain crop or cutting grass for hay. The inside of the curve is sharp, so that the user can draw or swing the blade against the base of the crop, catching it in the curve and slicing it at the same time."

Another request from a friend, this sickle weighs in at 122 faces and triangulates to 208.  Materials are the same as the cutlass.
