Roddio....made by Daiwa Seiko and yes...graphite. I haven't had the oppurtunity to play those or see those shafts in person yet. I believe they weigh about 105grams for the Stiff and 107grams for the StiffX. They are pretty pricey like most Daiwa Seiko shafts. I believe they run about $140 a shaft. I have no idea on the playing characteristics.
I do know those ONOFF Forged + irons that are at the ends of those shafts are very good though.
