Pugios and silver inlay

[LUCIUS ALFENUS AVITIANUS]

Thanks. Well, i know what's a loop, but before the answers, i don't have understod the use of that in making a silver inlay.

So, we make the loops to double the width of the wire. If roman use that kind of thecnic, a central line betwee the two "arms" of the loop can be visible with a microscope or so.
