The women aged 24 and 31 were apparently looking for trouble after a long night out in the city's Schöneberg district, the daily newspaper Berliner Morgenpost reported on Monday.
After trying to pick fights with several guests in the club Nachtleben they were kicked out by bouncers. According to police, the club had held a party ahead of the start of the Muslim month of fasting Ramadan.
The two women of Turkish descent then fell upon the 21-year-old Turkish man Firat G., who had celebrated his birthday in the club, at around 6 am on Sunday. As he tried to leave the scene, the two women drew knives and stabbed him several times.
The club's bouncers witnessed the attack and held the women until police arrived. The man was admitted to the hospital for an emergency operation.
