Well I tried today on the small map: I was running with my knife but all I got was one knife - kill.
Th other players saw me, laughed and than shoot me down from a mile away*lol
So all I want is the basic badge,I think that is possible, expert in knife kill I will never be*rofl
But thanks anyway for your advise, I will be seen tonorrow on the small map; so don´t laugh when you see a bunnyhoping player with only a knife in hand, it`s me

shot you some times XD , try to shoot and take knife when there are corners... my advice to not get killed so you can finally knife at good spots...
+ expert knife badge is possible

, though i would never get veteran pistol badge... got it though + expert if i had 700 pistol kills or something
