Could it be what Chuck would call a "double four-fold"? It seems to have 4 folds and to be lined with the same material.
No. Its a regularly constructed tie. All regular constructed ties are made with a tiny fold over the edge so as not to be visible when the tie might be turned over. The inside (hidden fold) is simply sewn together.
It's not a sevenfold, but still looks like a great tie. I'm currently wearing a Borrelli from Lance that's also like that in the sense that it's self-tipped and the inside silk has the pattern from the outside, but not a sevenfold.
