Shaving, Wet shave vs electric

A friend of mine used to work for Gillette pretty high up the marketing chain, and he told me they have invented the ultimate razor, that never dulls, never needs replacing, and will never see the light of day, as it is patented to fuck and locked away, allowing them to bring out more "inovations" to reel suckers in year after year

so much protection that he felt he could blab about it to you without fear of repercussions? i highly doubt they have invented a non dulling blade as they would have sold it and made a bomb replacing every single blade everywhere. but they don't because they didn't.
