What I think that means is the knob on the bottom of a sword scabbard.
There are such things and they look similar. I will look in more detail later but try to look up Roman sword scabbards.

Yes Shawn you are correct, that's what I meant. Someone showed me a picture of one a while back and it seems to match spot on. If it helps you in finding a match, item finds date 1-2nd century AD. I'll try and find some examples but i'm very unfamiliar with it.
What would be the purpose of a hole on both sides ?
