Roman Pugio

Ancient

The pugio is a double-edged dagger carried by soldiers of the Roman army as a sidearm, its design adapted from daggers used by the Cantabrian peoples of the Iberian peninsula before being standardized for Roman military issue. Its precise tactical role in combat remains debated among historians, but it served as a personal backup weapon for close-quarters emergencies when a legionary's primary sword, the gladius, could not be used, and elaborately decorated versions were also worn as a mark of rank and status by Roman officers. The pugio's association with violence beyond the battlefield is most famously tied to the assassination of Julius Caesar in 44 BC, when his killers are recorded as having used daggers of this type, cementing the pugio's later reputation as a weapon of political murder and, in some accounts, suicide, alongside its ordinary role as standard military equipment.

Wikipedia own Forging section places a large-bladed, standardized pugio pattern by the early 1st century; the dagger own design descends from earlier pre-Roman Cantabrian daggers, so this year marks the Roman army standardized pattern rather than the weapon ultimate origin.
