Knives in the case
The Exceedingly Rare Special Item group lists the Bowie Knife, Butterfly Knife, Falchion Knife, Huntsman Knife and Shadow Daggers. Here they come only in Gamma finishes: Gamma Doppler in several phases, Lore, Autotronic, Black Laminate, Freehand and Bright Water. There are no plain knives in this group. The same five knife types are in the Spectrum Case, but with Chroma finishes like Doppler and Marble Fade instead.

The weapon skins belong to The Operation Riptide Collection, and every one of them also has a StatTrak™ version. The Dreams & Nightmares Case lists exactly the same knives and finishes.
