How To Long Range Knife Glitch

I'll be teaching you how to do the the Long Range Knife glitch
you must be in a demolition match its the only game mode that it works in
Take out your primary weapon
Press 213 quickly then as soon as you press 3 with your left hand press and hold the LMB (Left Mouse Button)
If you did it correctly your knife should shake some and be making indents at wherever your aiming
It might take a couple of attempts to get it correctly
You can do 214 to shoot with a nade 215 to shoot with a c4
It doesnt work with binoculars it only shoots once
Sniper rifles dont work well because they only shoot once
The amount of knives you can fire depends on your weapon the amount of ammo you have on your gun is the amount of knifes that will be "shot"
The rof and recoil of the knife all depends on your gun I personally use the bizon to do it because of its rof and ammo
