The knife needs to be fixed

The knife needs to be fixed as their is so many times that i hit someone with a knife and it does not kill them, i hit someone 4 times before they shot me. my ping sits around 60, please fix the knife, i would have a video for you, however Geforce did not save the recording, however i sure a bunch of people have that save problem and can post one.

yes knife hit reg is completely broken. . . just play frenzy and the bots will miss half of the time

please fix your broken game, or do not bother updating it

It is the same with me.
I thought it was normal, but yesterday a bot killed me with the knife while I hit him first, but he didn't die.
