Why did we wait so long for the threshing machine?
This process is called threshing. As the husk is quite hard, threshing is a violent process. Traditionally, it was done with a tool called a flail, which is simply a short stick attached by a cord to a longer handle. The grain was spread out on the ground (yes, disgusting) and beaten with the stick to open the casings.
