Change the text of the knife (and i guess famas) to be more clear, as it stands it says this: "Unlocked trough operation"
Example: https://steamcommunity.com/sharedfiles/filedetails/?id=3834868283

But i just learned that its unlocked trough some tokens we get for the daily/weekly challenges? then it should say that instead of saying its unlocked trough the operation? 🤷‍♂️👍
