I just purchased yesterday a 1962 Slim Adj. and it had in it an old schick twin DE blade. I have never heard of or have ever seen one. Has anyone heard of this? It's basically 2 blades stacked on each other but one is a tad bit more narrow.
Seems to me, I do remember twin DE blades. If I remember correctly, they came on the market shortly after Gillette introduced the Trac II. They were an ill-conceived attempt to capitalize on Gillette's latest "innovation". I think there were also twin injector blades.
