Went to the Renaissance Faire with  roaringlion and  elliedachshi and I picked this up from a vendor.

A replica of a Greek Kopis (Falcata in latin). The sword was used in a chopping motion during close combat. It wasn't the standard issue for the Spartan army during the classical period, but was more common amongst all Greek forces later on.

Fairly cheap but it'll go well with my costume.
