The pugio was a small dagger used by Roman soldiers as a sidearm. It seems likely that the pugio was intended as an auxiliary or backup weapon, but it found many uses, especially as a utility knife. Officials of the empire took to wearing ornate daggers in the performance of their offices, and some would wear concealed daggers as a defense against contingencies. The dagger was a common weapon of assassination and suicide; for example, the conspirators who stabbed Julius Caesar used pugiones.
