There are also a SHIT TON of Clothing Choke holds that can be very useful, in particular the T-Shirt and Hoodie Choke.
You can never have enough empty hand skills folks!
Personally I think Street Combatives/Boxing combined with cherry picked techniques from all the major disciplines: Muay-Thai, BJJ, Krav-Maga and Kali offer the Armed Civilian the best chance, but as with everything in life, find what works for you and TRAIN HARD!
I highly recommend Southnarc (Shivworks) for Realistic Street Fighting Training.
