About the Stiletto Knife | Ultraviolet
Stiletto Knife | Ultraviolet is a Rare Special Item knife that drops from 2 of the 42 CS2 weapon cases: Prisma Case and Prisma 2 Case.
The earliest of them is the Prisma Case, released on 13 March 2019.
Each open has a 0.0093% chance (about 1 in 10,769) of pulling it, as one of 28 Rare Special Item finishes in every one of those cases. One in ten of those drops is StatTrak.
It sits in tier 5 of 5 (Mil-Spec to Rare Special) and ranks #7 of 45 finishes in the Prisma Case by top-wear Steam price.
Its Steam price runs from $190.04 to $442.75 across wears, against $4.11 to open the Prisma 2 Case (case plus $2.50 key), so every wear is worth more than one open.
