I appreciate it. This was a complex post to put together, and is a complex topic in general like you mentioned. It took me some time to compile in a way where I was happy with the end result. To further clarify for the community, in my first paragraph for my first point, "finished mechanically" means that there would be no final polishing with a handheld rotary tool by a craftsperson. The bevel would be entirely automated, entirely mechanically finished. The alternative is having the final polishing step being guided by hand, using a handheld rotary tool for polishing, which is what I think we see with Cal. 1315.
