Hi there, i am piecing together a BUDGET pirate costume, the sword i ordered was from amazon (picture below), but when it arrived i instantly saw that, although it was good quality for what i payed, the blade would flex and bend with the smallest of movements. So, my question to you is, What can i do about this? Is there a way that i can strengthen the blade somehow? maybe securing something to the spine of the blade to make it studier? The blade itself is not hollow, and do try to remember that i'm on a budget. Thank you in advance for any and all suggestions!
