I've encountered a problem playing with bots.

I'm pretty sure the creator didnt expect any same palyer to do this but sometimes when im bored, I do a knives only match with about 25 bots, its mad! But the problem is the bots dont seem to knwo they have their knife, they either try to punch me or pick up a knife from off the ground. Is their a away to make them use their knives without haveing to kill me and steal mine? (Btw, rambo mode with 25 bots with knives running after you is insane, they just come from all sides [:D])
