I'll contribute as well. I currently have 4:

Hart Steel 5/8 Round Point in O-1 Tool Steel
Thiers-Issard 4/8 Semi-Round Point in C-135 "carbonsong" Steel
Ralf Aust 5/8 Round Point in Mild Steel
Iwasaki Kamisori 50mm (~6/8 - 7/8) in Swedish Steel

I also have a Muhle R89 DE...there is only one problem. Up until 2 weeks ago, I was still in the land of cartridge razors. I have a really bad case of RAD. I would love to be able to work on old razor and restore them, but at the moment, I do not have the space for a kitted out work area...

I'm amazed at the dedication I see on the forum with regards to restoring old pieces. But the best part is taking something that has to be done everyday and turning into a passion and hobby.
