There are glass fractured blades that form the same edges and diamond scalpels too, all of them show brittleness issues to lateral moves especially. The physics of steel cutting edges get very complicated in general as can be shown by an example of how human hair can damage steel here: https://www.reddit.com/r/EngineeringPorn/s/6xHn8TQEtK

I tend to geek out over the topic of cutting as it’s endlessly complex from biological matter all the way to cnc.
