Morning,
I found this handle steel chart here that lists it as ” CV Steel:1095 Steel with added Chromium (1%) and Vanadium (.18%) to improve hardening and strength. The term usually refers to knives made by W.R. Case & Son but others also use the steel. It is sometimes referred to as a semi-stainless carbon steel due to the added chromium.”
Id probably go with something like a scotch brite pad to minimize material removal but a fine grit sandpaper would work slightly better if the pitting is deeper. Since it is listed as a semi-stainless carbon you may want to consider a protective coat of something like a 3-in-one oil. Sometimes just a light rubbing with 3-in-one can remove surface oxidation without having to resurface the entire primary bevel.
Aloha, Cliff
