From Samsara site.. and I quote..
"True Shafts are the ground-breaking low deflection(squirt) performance shaft from Samsara. Seven years in the making with countless trials led us to re-invent the modern ferrule. This one piece hard maple shaft with plenty of magic inside will change your mind on what a blend of tradition and technology can offer in playing performance and consistency.
All True Shafts come standard with Medium Samsara Layered Playing Tip."
I take one piece to mean solid? Maybe it's a play on words but this does not sound hollow to me?
