Scythes and pitchforks were stereotypically carried by angry mobs or gangs of enraged peasants. The process usually involved reforging the blade of a scythe at a 90 degree angle, strengthening the joint between the blade and the shaft with an additional metal pipe or bolts and reinforcing the shaft to better protect it against cuts from enemy blades. At times, instead of a scythe blade, a blade from a hand-operated chaff cutter was used.

To resolve those issues, one economist proposes a cost-allocation model that would determine the optimal allocation of USPS's common costs by finding the share of costs that would maximize USPS profits from its competitive products. Postal regulators could use such a cost model to ensure that the Postal Service is not abusing its statutory monopoly by subsidizing price cuts in competitive product markets with revenue obtained from the monopolized market.
