Yay! Congratulations on ditching the carts and switching to DE. Cartridges are so expensive and DE blades are super cheap. You will save tons of money for sure!I'm 60 and been DE shaving for just over ONE month after using cartridges of various kinds since 1977.
Oh! Oh... Okay. Good start.I have very quickly accumulated a fairly broad array of vintage Gillette razors (fifteen-ish spanning 1918 to 1971). I also have five new razors.
Welcome to the forum and enjoy your new rabbit hole!
