The term kopis (Ancient Greek: Κόπις) in Ancient Greece could describe a heavy knife with a forward-curving blade, primarily used as a tool for cutting meat, for ritual slaughter and animal sacrifice,[citation needed] or refer to a single edged cutting or "cut and thrust" sword with a similarly shaped blade.
