"KZN" razor

My second job.
Carbon steel, hardness - 56-58 Rc/
Handly - plastic? pins - inox+bronze
Сomposition of the steel:
C- 0,96 - 1,03
Si - 0,17 - 0,33
Mn - 0,17 - 0,33
Ni - to 0,25
S - to 0,028
P - to 0,03
Cr - to 0,2
Cu - to 0,25
Fe ~97

May suggest any your analogues of this steel?
Shaving is a very soft, but only during grinding with electrical tape. If you sharpen a very sharp (no tape), the edge quickly is jammed. Most probably it is a violation of steel heat treatment technology. I may be overheated when grinding the edge, but this is unlikely.
