How long can the core in the blade blade of a sword be before it fails flex if I'm using 3/8 fiberglass? I'll have a box plus 2 more layers of foam over the striking edge.
I thought it was 22.5" but I can't remember exactly, and I dont wanna make it then have to rebuild it again. Mind you I need the length of the CORE in the blade, not the end product. Also, I've got a 10" Grip and 2" pommel, so Overall length with a 22.5 inch blade core SHOULD be 37".
