Quite the video you sent along, 3D Anvil, and thank you for the effort in doing so! We can offer the following in an effort to help you with your question:
Edges cleaved from obsidian glass produce the sharpest edges (at least to the extent of our awareness). Obsidian glass material is capable of producing edges many times sharper than any edge composed of steel.
They say that an expertly cleaved obsidian cutting edge can have a total thickness of only 4 nanometers. Assuming a properly conducted sharpness test and, if said obsidian was subjected to that sharpness test, such an obsidian edge would then produce a theoretical BESS test result of 2 (total thickness = 4, radius of edge = 2 nanometers). Apparently, the obsidian scalpels we tested some time ago weren't as expertly cleaved because they ran BESS 3 - 5.
With consideration for the above, we feel your "bogglement",
