New Iwasaki tamahagnae razor

Good day gentleman.

I was wondering if Iwasaki are making any tamahagnae kamisoris any more?
I know that his student is making the swedish steel type but I've yet to see any tamahagnae ones except those on ebay that are going for silly money?
Also for those that have both are they much different in shave quality? I have the baby size (45mm) and I find it wonderful to use. The tamahagnae ones that I've seen are all full size so there's obviously going to be a difference in feel to my size but if two where the same size would one be able to tell the difference in a blind test or are you simply paying extra for the process, workmanship, materials etc.

Many thanks.
