When was the dagger vs the pugio used

[stevesarak]

I’m sure this as been asked and answered before, I looked around but couldn’t find any thread on it, so any info or a link to it would be appreciated.

I’ve noticed a lot of 1st century daggers as well as pugios, did some legionary carry pugios and some carry daggers? As far as your basic kit, when was each used? Was the dagger carried as much as the pugio or do we even know?

What do we know about the daggers.

Thanks
