Size of Flails

How many hands do I need to use a flail? According to the master gear list (p. 37 and on the GM sheet) a flail is carried 2. However, the player deck and the table on p. 41 say it’s carried 1. Which is correct?

Do you want to actually use it or just flail around?

Well, one of my players is rather fond of that thing, and there are some critters in need of flailing …

Ack.
Just this once, let’s go with with the player’s deck: hand/carried 1

Thanks!
