there is a legit Anti Knife [FREEZE] but it is most VIP sections. I have it, and yes, it works flawlessly. This is not the only way to stop from being knifed. There are plenty of good anti knife codes. Look for the one that says it locks player animations, that one works very well. You wont be able to climb or crouch, and when you die, you dont fall down (yes, people do keep shooting at you like a bunch of idiots) but it does prevent a hacker from knifing you.
