Hi there, I don't know whether Ulrik (AKA Koraat) is a member here. With regard to how his razors perform: they are absolutely top notch and don't have to fear any comparison to vintage Solingen blades :tu . In fact, Ulrik uses 1.2210 silver steel for his 8/8 blanks and 1.3505 ball bearing steel for his 6/8 blanks, which have been made against his specifications by one of the remaining drop-forging companies in Solingen. He grinds and heat-treats the blades himself (he comes from a goldsmith background).
And he's a true gentleman to deal with :) (and, in case you worry, not related or in any other way affiliated to me ;) ).
Cheers
Jörg
