What, forget no. I just mean wooden or foam (the nerf swords actually work well too)
Make boffer swords then, they are dirt cheap. All you need is a pvc pipe, duct tape, spray adhesive, sand paper, and a foam pool noodle. Also possibly a car shammy or some kind of spongey foam.
I made 2 of them and play with my friends or sister and sometimes bring them over to my friends and have like 8 people fighting, its really fun
