Does anyone know what type of stainless steel is generally used for common butterknives?

TryThey seem to have the same temper as carbon spring steel, as I can't bend them. Looking for guidelines on heat treating, as I want to hot-forge the handles to make jaw harps, and might have to restore the blade's temper for springiness of the tongue.

See if the butter knives are magnetic.
