Counter-Strike: Global Offensive Knife animation problems

[SneakyTurtle]

So in the past month or so i have been having a problem on the CS:GO servers.
Specifically Jailbreak.

The problem:
When i am a T/CT and attempt to knife a CT/T(opposite team) sometimes the hit doesn't register and thus i didn't damage anyone.
The animation and the sound plays off(sometimes blood appears too).But as stated before i don't damage the enemy.
If anyone knows why this is happening feel free to comment on this post.
At first i thought it was because of ping but it happened to some people who have 50ms and lower.
P.S.
I'm not sure if this is a glitch so i just put it on this part of the forum.If necessary ill rewrite it on the correct one.​

This has been an issue since the game came out, and is even a thing in other source games. In CSS, the knife just doesn't make any sound at all, including the swing sound, if it doesn't deal damage when it should've.

It's most likely due to interpolation and lag compensation. So your client registers a hit, but when the server runs its calculations on movement and what not, its like nah he's actually 1 unit outside of knife range, so I'm throwing your knife swing out the window, cya nerd.
