Hello everybody! Last year's renaissance festival was awesome because I mostly completed my costume including this awesome shield! But after the event was over my friends told me I kept accidently bumping into them with it without me being able to tell and it is just overall cumbersome to hold all the time so is their anything I can buy so I can just carry/wear this on my back? There's this weird iron bit sticking out here (zoomed into in the second photo for reference) and I have no idea what that's for and I was thinking I can loop something through that? But I'm unsure if it will break or not. Any suggestions or ideas?
