The gamma-shaped hilt dagger (in Italian: Pugnale ad elsa gammata) is a type of bronze dagger typical of the Nuragic civilization in Sardinia. It owes its name to the inverted gamma-shaped handle. Used for animal sacrifices, they are widespread in Nuragic sanctuaries.
They are dated to the early Iron Age and are often represented in the Nuragic bronze statuettes on men's chests; according to some scholars they appeared as early as the Late Bronze Age. It was a weapon with a strong symbolic value, a sign of belonging to the social body.
