Lol that is so funny, I just bought that fin new at Windance Board Shop 2 weeks ago. It's a great fin. It is called the K-one free wave fin. Mine is a 27cm fin. I ended up gettin mine in a power box style, as the pic here shows it in Tuttle box. This is an awesome fin. Check out the K-one Freeride fin, I have that one too in a 38 cm size. These fins are very very fast.
