How many instances of solid fiberglass core swords breaking their core do you know of? Personally witnessed, not just heard from a friend.
Background: At Sotahuuto, they have banned fiberglass cores because they had one break and splinter badly. I couldn't get more details, so I expect it was a hollow core. I hope to convince them to allow solid-core so we can use our weapons and they can have weapons that don't break (I broke two of their swords over one weekend). Having some numbers on breakage in Belegarth would be helpful.
