I'd guess any razor from a reputable maker would do as all are hardened to around the same point, 62 Rockwell I believe. Someone more knowledgeable will clarify that shortly. There really should not be massive differences in hardness. In vintage I have not found great differences in carbon steel and stainless steel razors either as far as honing goes. I'd say get a variety of vintage razors in decent shape and have at her.
