I'd wager that razor blades and scalpels and many other things sharper than kitchen knives are made by machines. Sometimes we don't automate fully expensive things because handmade is also a premium, not necessarily because if we were to dedicate engineering resources to the problem it would be impossible to automate. That said there are things that machines currently can't do despite good efforts to solve the problem. That's true
