This will be a thread as to why the golden knife should make a resurgence to Trouble in Terrorist Town.
In the current state of the one-hit knife, it is impossible to tell whether or not you should stay away from someone with their knife out. I understand this is intentional, by design. If you're alone with an innocent as a traitor, and you have a one-hit knife, the other person will not know at all whether or not you actually have one. There is absolutely no way for them to find out, other than them dying. However, people may like the re-addition of the golden knife, due to the "fun factor" of it. The traitors, at the moment, have a very easy way of hiding their one-hit knife. It's not very fun at all. With the golden knife, it adds a level of taunting to the innocents. For the one-hit knife in the game at the moment, holding your knife out shows no threat to anyone. It's too easy for the traitor to get a kill on the innocent. At least with the gold knife it gives the innocent a chance to kill the traitor.
Another thing is about the nature of TTT originating from GMod. In the GMod version, anyone with a knife is considered a T, as innocents cannot acquire a knife. Since in CS:GO everyone is given a knife, there should be a way to identify if the traitor has a one-hit/gold knife.
I know a lot of replies to this post will be along the lines of, "there's no point in adding it back, we wanted to buff one-hit knife." I just wanted to put my opinion out there, and hopefully see it put back into TTT.
