Add a switch blade that is able to be opened up with does a little noise and it does the same damage as a normal knife but is way faster and when you sneak up behind someone using the knife you kill him instantly but only when you sneak and hit him. The range should be the same as a normal knife it should spawn in uncommon to rare chests
I mean, we have a lot of knives. We have "normal" knife, tactical knife, butterfly knife, kitchen knife, and a few others. I mean, why not? But why do? Not really any point.
Tactical Knife does double damage on backstab and Fade Army Knife does double damage on backstab as well I believe, and that's enough to kill someone in 2 hits, so I don't think we need those. Besides, melee has either no equip timers or have extremely minor amount
