This ancient knife wasn't a box drop or an event reward — it came from a 2,499 Robux gamepass during the 2018 Halloween Event. That pass has been offsale for years, so no new copies are entering the game; every one you see is trade-only. Stable for now. If you want a Halloween knife with more trade movement, Aurora or Vampire are the usual comparisons.
Batwing is an Ancient knife in Murder Mystery 2. Its combined value is 43.5, #10 of 20 ancient items and #197 of 921 valued items overall. Demand is low: it sits in inventories for a while, and buyers often ask for a discount.
