Pic related: It's of a Dacian Falx.
>The Dacian falx came in two sizes: one-handed and two-handed. The shorter variant was called sica[2] (sickle) in the Dacian language (Valerius Maximus, III,2.12) with a blade length that varied but was usually around 16 inches (41 cm) long with a handle 1/3 longer than the blade. The two-handed falx was a pole-arm. It consisted of a 3 feet (0.91 m) long wooden shaft with a long curved iron blade of nearly-equal length attached to the end. Archaeological evidence indicates that the one-handed falx was also used two-handed.[3] http://en.wikipedia.org/wiki/Falx
