Ringle CamTwist skewers?

[Double-E F]

Are these the real ones, or were they also copied at some point?
I am in doubt due to the fully threaded steel axles..

The first ringle cam twists had that fully threaded main axle. I've seen & owned several sets like that

Very early ones were fully threaded, M5.
Very very very early ones were fully threaded 3/16".
They look ok to me
(see link in my footer).

There are some comments about the first ones to be with fully threaded steel rods

Fully threaded are genuine but early type. Picture here shows OMAS copies, see the middle of the pivot is hollowed out. Nut is more tapered along its length than a genuine one.
