Just curious: why do you need the blades to be precision ground?
And welcome back!
Hail St. Roy, Full of Grace, The Schwarz is with thee.
Blessed art thou among woodworkers, and blessed is the fruit of thy saw, dovetails.
Holy St. Roy, Master of Chisels, pray for us sharpeners now, and at the hour of planing.
Amen.

Glad to see you found a source, but I think you are out of sequence in your specifications. I am not a metals engineer, but I did make plane blades and cutters successfully as a business for over ten years. I started with precision ground stock, performed shaping and rough edge grinding BEFORE heat treating. O-1 steel requires oil baths for heat treating. Warping can occur during this process. Sharp edges can fracture. Working the metal after heat treating, which includes hardening and tempering, can cause issues. I limited my processes to light edge finish grinding and sharpening. The grinding was done with frequent quenches to keep the temperature of the metal cool.
Unless you have complete control of the process, someone can inadvertently ruin your temper during surface grinding. I hope they really understand your requirements and counsel you accordingly. Good luck.
