Mr. Mark, I am sorry I cannot shed light on properties of straight razors.
Only recently I received an old, totally destroyed German straight razor. The guru of the local straight razor forum told me that it was a high quality product (N. & H. Clauberg, Gold Fish, Solingen). The handle is of horn, decorated with silver ornaments. The guru spoke of it as an "old lady".
I decided to re-purpose the razor torso and shaped it to a letter knife (letter opener). Because the carbon steel is really very hard I used my low speed, water cooled fine diamond wheel. Re-shaping of the straight razor impressed me. It is very fine steel and the spine is quite robust.
The picture at the bottom shows the degrees of hollowness of the blade.
