About the Skeleton Knife | Ultraviolet
Skeleton Knife | Ultraviolet is a Rare Special Item knife that drops from one of the 42 CS2 weapon cases, the Fever Case.
Valve released the Fever Case on 31 March 2025.
Each open has a 0.0093% chance (about 1 in 10,769) of pulling it, as one of 28 Rare Special Item finishes. One in ten of those drops is StatTrak.
It sits in tier 5 of 5 (Mil-Spec to Rare Special) and ranks #3 of 45 finishes in the Fever Case by top-wear Steam price.
Its Steam price runs from $188.08 to $552.04 across wears, against $3.38 to open the Fever Case (case plus $2.50 key), so every wear is worth more than one open.
