My razor

It is getting hard for me to find replacement blades for my Trac II razor. I have had the thing for about two decades now and it is admittedly looking pretty funky. Problem is the only alternative to my double blades is to buy cheap disposable razors or some of the new "four" track razors. These things look like ugly Japanese sports cars and have names like Quattro or MPower. The Trac II razor must have been introduced in the mid 1970s. I know that because my wife and I recently rented some of the classic Saturday Night Live shows from that period. In one show there is a "spoof" ad touting a triple track razor. It was amazing to watch the fake ad 35 years later. The end line went something like. "The Track III, because you are just stupid enough to buy one." Now I think of this SNL ad every time I go to the store and am faced with a wall of track three and four razors. God, are we really that stupid?
