Not only do streamers look cool while swinging the machete, they're also useful for identifying your weapons. I mean; while I'm swinging my machete through a crowd of Legionnaires, it inevitably get's stuck in someone's skull and sometimes it takes more than just a quick tug to get it out... *rolls eyes* I mean we've all been there, right?... So after the fight the streamers make it easy to go back and retrieve my machete among the carnage. Having them glow in the dark is a huge help when the fight lasts past sundown.
