Just to be clear, the blades in at least Episode 3, were texalium wrapped carbon fiber rods (from a company called Kilwell in New Zealand) and not just straight up carbon fiber rods. Regular carbon fiber rods are absolutely horrible for dueling but the texalium wrapped ones are pretty durable (but of course, can still break if enough force is used).
Oh hey that's something I didn't know. Depending on price I may inquire with 'em, being local and all - thanks for the info!
