I have 135 dollars, and I want to buy a knife. I need some help deciding.

So I've come to the point where I'm enjoying the game quite a lot and I can manage to drop 30 kills fairly consistently, I want to buy a knife with a budget of 135 dollars; I'm not too aware of what's the 'best' knife but I'm sure there's a good knife I could get for 135 USD. Please drop your recommendations down below, I will update once I have bought. Thanks!
