Yep - STC's on it.
Here's some pics of both.

I run a bead of electrical tape around the blade - (black on the carbon above).
I've taken the tape off the balsa blade to show the edge.
I'm 6'2 and 104kgs. I give all me gear heaps of use and treat it all hard. I'm not one to wrap my boards and paddles in cotton wool. They're art and they're surf craft - use 'em.
I've had no problems at all with the paddles.
TIP!
