At least it was never a problem to buy DE blades for those old razors. And I don’t think we will have a problem for the foreseeable future. I think we all owe a debt of gratitude to the shavers in certain huge markets like India who never accepted cartridge razors.20-30 years ago, I still had a few Gillettes from before then. Other than trying the Trac II, Gillette's first real attempt to kill of DE shaving, it's been DE or some unhappy periods with electrics during times of my career years.
