I don't know if Sheffield steel makes for a better blade, but it does feel a bit better than the Solingen. I'll try to post a pic. later today.
Sorry to hear about the cuts. I try to see where I put the razor on the sideburns which is not always attainable, but I hear the blade has to be moving before it touches the skin.
Don't get discouraged as it takes a lot of attempts to get it right.
I had my third shave with the str8 a couple of days ago and it went without any major disasters, but I still don't feel confident enough to go for the chin all the way. I do 1 pass and finish up with a DE.
