For the Greenskin career, see Choppa
A Choppa is a crude blade fashioned from bits of discarded metal that is used by the Greenskins, particularly Orcs. Choppas are renowned for being very unwieldy, not always sharpened, and extremely heavy. However this does not stop the Orcs from inflicting large amounts of damage with them. It is easy to see why they are called Choppas.
The incredible weight and lack of balance in the weapon makes it hard to wield in both hands for a human, however most orcs are able to carry one in each hand, and fight proficiently with both of them at the same time. That fighting style is very common among the choppas, which is one of the reasons they have been named for their weapon.
