---Proof in description--- Yep,the price has to be nerfed. Its impossible to sell for 3 keys , and alot of people are selling it for that amount. It will only sell once you go under 3 keys.

Proof :

-Sellers for 3 keys

I did not note buyers under 2 keys or sellers above 3 keys since they're way out of the price range, also sorry for the lack of proof , there is not alot of market for this knife.
