If you were opening Mystery Box 1 during Season 1 back in 2019, Rune was one of the legendary knives you could pull, and it's still unboxable today. Its draw is mostly the rune-covered look and the early-season origin, not trade drama. Value history isn't recorded, which fits a knife that just holds its place. Neighbors on the value list include Biogel, Candy Corn (2025) and Checker.
Rune is a Legendary knife in Murder Mystery 2. Its combined value is 0.33, #77 of 89 legendary items and #719 of 921 valued items overall. Demand is low: it sits in inventories for a while, and buyers often ask for a discount.
Closest in value: Biogel (0.33), Candy Corn (2025) (0.33), Fade (0.33). Use them as a benchmark for a fair one-for-one trade.
