I'm not familiar enough with A1, but chrome plating could be used. The problems arise from the expense of the plating operation and wear and tear exposing the underlying metal. Some plated blades at Kodak began corroding, so they stopped that 'experiment'.
In fact, ones set of blades was made of cheap iron with a teflon coating. It eventually began to wear and then corrode.
You see, the surface of paper is quite surprisingly abrasive and does a job on the surface of a blade.
