I knew Schick and Gillette had made them, but I had never seen any before from Personna. Must be old stock from the 1970's

Paul, Personna made Injector blades until very recently. In fact, I haven't heard that they discontinued them, but I don't see them listed recently.

These blades are the Injector II/Twinjector blades, which pair two blades close together, trying to approximate a Trac II. I don't know how effective they actually were. (I actually have an unopened NOS package of these blades and I have never tried them.)

(I'm going to watch this one.)

I meant twin injector blades, since I had never seen any before from Personna. I don't think they'll stop making single injector blades, at the very least without a key, for barber/salon and lab use.
