Sounds like they put one thread of Kevlar in there, and then claim more than reality, huh? Order canceled, thanks for the info.

I forgot about my sea urchin incident until reminded by your story, Steve. I got a bunch (about 12) of those sea urchin spines in my foot as well, also on a P.R. reef.
Couldn't get them out. You know how those things are. They are very crystalline and needle-like. So they go in easy, but when you try to take them out, they shatter. Pain in the butt basically, cuz they ain't coming out.
It was bad timing too, cuz someone had just "stolen"/borrowed our boat and I couldn't chase them! Those things were in my feet for weeks until they dissolved.
Worse was the time I got some in my head while diving and looking under a ledge.
I raised my head right into one (long spined sea urchin, Diadema, I think) and got about ten right in the skull. I felt pretty stupid coming out and explaining ten 4 inch spikes in my head to the dive master.
