Posting this here for fun:
In the Science.org whitepaper "How Hair Deforms Steel" there is a comment regarding BeNi alloy razors. Apparently some were made in the 70s and they were neigh indestructible. It would be cool if some DE BeNI blades were made! How to make this happen? It is a literal tragedy in terms of millions of tons of plastic and steel waste in the past 50 years since this breakthrough.

In the early 1970's I worked for Cabot Berylco in Reading Pennsylvania. Their main product was CuBe alloys for the electronics industry but a secondary product was BeNi for the wood pulp industry because the crushing plates would wear out slower than any other metal. One of the major razor/shaving companies had us make razor blades out of BeNi which were nearly impossible to sharpen but when the blades were finished the tests were incredible. The blades never lost an edge and you could shave for years with changing them out. The project was shut down when the razor company realized they would go out of business if everyone stopped buying replacement blades.
