I'm not affiliated with their team in anyw ay, but I'd guess the reason for the edges is to give that gear a little extra support all around. The edges bow out slightly around the axle and then go back in probably to save weight.
So now for some questions: CNC milled or waterjet? To me it looks like it was cut with a waterjet. Also- did you get the idea for the curve from a stress analyzation program? We had an engineer on our team once who had the software and allowed us to save all kinds of weight.
Anyway, great looking part and keep up the great machining.
