My curiosity was piqued after reading a member's review of a titanium razor on a now closed thread - yes titanium is a polarizing metal. In any case I went to Wiki and learned all sorts of fascinating things about titanium. My conclusion is that the use of titanium in safety razors is essentially a marketing ploy - its a vanity metal in that it is perceived to be rare, exotic and expensive thus enabling the producer to obtain premium pricing, (although Italian Barber is about to kick the underpinnings out from under that market. Assuming they are able to produce their promised sub $100 titanium razor in sufficient quantities to meet demand.) From what I can see there is nothing about the strengths and weaknesses of titanium that makes it necessarily suited nor unsuited to making safety razors.
