I don't know about the big one, but I can tell you something about the normal size Blue Wonder. I was given a Blue Wonder razor recently by my mother. It is a 5/8ths half hollow which had never been honed. It honed up really easily. Usually it takes me three or four tries to get the edge right, then a few more shaves to get it perfect. With this razor I got it shaving really well with just two tries.
As for the shave, all I can say is it felt great.

I can say the Blue Wonder razor is a great shaver and it can make a half competant honer feel like a pro.
