I've heard a second hand story about some titanium razors made internally at <large razor company> which were given out to employees as gifts. They lasted for years, but could never be released as they simply wouldn't be able to turn a profit.

They lasted for years, but could never be released as they simply wouldn't be able to turn a profit. That seems unlikely to me. Properly heat treated steel is considerably harder than titanium. This is why titanium knife blades are generally limited to niche applications (like dive knives, although that market is being contested by modern rust-proof steels like H1). Material hardness is one of the leading factors in edge retention.

  But hair is so soft compared to titanium, seems possible that the much greater flexibility might make up for the poorer edge retention.

  Seems like a thread where people might be interested in https://knifesteelnerds.com/ https://knifesteelnerds.com/, which has made the front page on HN on a couple of occasions. I have no relationship of any kind, beyond finding it interesting.
