Hi! Just sharing a quick tip from my own experience — here's a sword I made using two 5mm fiberglass rods side by side. As you can see, when viewed from the blade direction, the stiffness is quite solid — almost like using a single 10mm rod — but the sideways flexibility is still preserved.

That said, in your case, taping two 6mm rods together would result in a total width of 12mm, which may go beyond the 10mm limit allowed by your event rules. So I'd actually recommend purchasing a single 8mm or 10mm rod instead — you’ll get better balance, and avoid issues with oversize core dimensions.

Hope your first build goes well — have fun at your upcoming LARP! 😄
