I don’t know what that is supposed to sound like, but it does not sound like a knife at all. It is one of the most annoying sounds I have ever had to listen to, and the fact that it happens every time you use the knife makes it worse.
Also fix the sound on the pistols they all sound like they’re suppressed! And really sound is everything when contributing to the ambiance of a game. I don’t want to use a .357 magnum and have it go pew pew pew like a suppressed 9MM.
