I understand how many people feel about it. The thing is, if you attack anybody (shoot, or melee) and it doesn't kill, everyone becomes alerted. If they nerf the knifes so they can be retrievable, they become useless for the stealth build. what they could do is increment the chance of you finding knifes on enemies... or make it a perk. knifes for me where a get outta jail card lots of times. My hacks were cooling down, a headshot wouldn't kill (by my calculations), about to be spotted: Last knife = ooof I'm saved. I like it as it is, but yes they should add cheaper knifes on vendors at the least.
