Hi there, I'm curious about the origin of open comb vs. slant bar, and specifically why Gillette's first razor used an open comb. As far as their transition to the straight bar in the late 1930's, I have seen ad copy for the Tech that the straight bar was "safer," and I've also seen it said that the straight bar was cheaper to produce, so a win-win for them. If all of this is the case, I'm curious why they didn't use a straight bar from the beginning.
Was it because the open comb was felt to give a superior shave at the turn of the century? Did Gillette think a straight bar wouldn't work? I ask because I started using an open comb (New) for the first time in the last few weeks, and I find it the best razor I've used. But aside from how they how well or not well they actually work, which is subjective, I'm interested in how people thought about them at the time they were produced.
