I received the razor today and gave it a try. My face is very red, but not really nicked, just abraded.
I started with the gillette 7 o'clock double platinum. It was not sharp enough, so I tried an astra. I have two feather blades, I have a feeling I'll be relying on them.
My face is very red and irritated, but the shave is very close. The fewer passes, the better. The lighter the touch, the better. For me it seems a sharper blade is better than a duller, the astra seem to be fairly sharp.
