There is a couple of different versions of these particular SharpEdge blades. I still have some of the old ones that a few people enjoyed but honestly I found them to be needlessly harsh. I believe the newer ones are said to be much smoother but I have not experience with the newer ones myself.
The ones you have are from the new batches. I will have to try these ones out soon.
I enjoy the Nivea lotion. I will have to pick up a new bottle. My ones are as old as the hills and probably no good anymore. lol
In regards to blades it sometimes also depends on the particular razor and your hair and skin type as well as technique. It's really a journey.
It's good to hear another vote of smoothness for the updated SharpEdge blades though.
