Blackthorn doublepoint needles. I've now used them quite a bit, and I'm still not sure what to make of them.
On the positive side, they are incredibly light and have very sharp points: two features I prize in dpns.
On the negative side, their clever carbon fiber construction leaves them with a slightly bumpy surface. In fact, I suspect that if you looked at them under a microscope they would appear serrated. The surface feels good on my fingers, but I'm noticing that it causes yarn to fuzz up very slightly while knitting. Overall review - Mixed.
