Not sure what you are showing us.
Yes, that's a carbon head tube.
Yes, that's what they look like.
A friend of mine just wanted to know if this condition of the head tube is normal (since for example the cross-cut and some vertical-cut are a bit deep).

Cut?
Thats the edges of the pieces of carbon. There's no cosmetic top layer on a steerer.
That's pretty much what your frame would look like with no cosmetic layer or clearcoat/paint.

Thank you very much for this answer.
So, for you it is not broken and it is absolutely safe to ride, right?

If you've damaged it it will be evidenced by a compressed ring in the carbon around the area where the compression washer contacts the fork (top bearing).

Ok, I understand and It sounds to me convincing!
In the meanwhile these pics were emailed to Canyon for an answer.

Canyon says that the condition is so as it should be: absolutely normal!
That deep cross sections are normal, they come from the process of "baking" (or "cooking"?) of the fork in the chimney (is that the right word?!).
