Abstract: A cold forged cylinder reel tooth adapted to be mounted to the cylinder of a threshing mechanism includes a threshing portion, a tapered seating portion and a fastening portion. The threshing portion includes identical symmetrical double-edged surface blades which are reversable to provide that the opposite unworn edged blade is positioned to engage the grain when the first edge blade is worn beyond practical use. The tapered seating portion permits proper indexing of the reel tooth 180 degrees to permit the unworn opposite double edge surface to engage the incoming grain in the threshing mechanism and the fastening portion provides rapid mounting and demounting of the cylinder reel tooth from the cylinder during the indexing operation.
