The pugio blades had become much larger and the pommel expansion on the handle had become crescent shaped in the second century, where they seem to have been rather mass produced in comparison to the individual style they had before. These later daggers seem always to have been carried in 'frame type' sheaths. The pugio came out of use in the course of the third century.
