[TUTORIAL] How to do the knife glitch.

Hi, Since it's already released, I'll release it, because I found out this glitch 3 months ago, probably found it first.
Looking for rep and thanks.
1. Equip weapon that can attach/ unattach silencer (example: mp5)
2. Find a weapon on the ground, after you kill someone, or practice in practice channel escort mode
3. Switch the weapon, so you have the other weapon, and your weapon is on the ground
4. Press 3 to bring out your melee, or 4 for grenade, 2 for pistol, 5 for bino or c4.
5. Walk over it, simply press w
6. Right when it says pick up weapon, press w and g, you run and sprint, and pick up the weapon
7. On the bottom it should say the melee weapon, pistol, or nade you are glitching, but you are holding your gun
8. Press V
9. Shoot and simply own.
Repeat the steps as much as necessary, kindof a hard glitch.
Remember to thanks and rep
