I remember reading about the development of Gillette's Mach 3 blade in the book "Good to Great". From what I remember, the spent considerable money in developing the tooling required to manufacture those blades. I think that razor has been around for quite some time now and maybe some of that tooling is easier duplicated now, but it seems like a market that would be very hard to enter because manufacturing a razor that could compete on quality and convenience would be very expensive to do. From reading some of the comments here, it sounds like DSC's razors are not nearly as good as Gillette's and they are able to sell razors mostly because of their marketing, which confirms what I had thought about new players coming in. I was less skeptical of Harry's because they specifically including messages in their marketing about how they took over an existing manufacture.
