Good info! I'll remember the blow dryer trick.I used the same cologne today, I prefer the Vintage Injector Blades like the Schick Plus Platinum, Schick Ultra Platinum, Schick with Krona Edge and Gillette Injector blades, and didn't care for the Personna 74's. I'd suggest giving one a try, injecting it in a Razor which already contains a blade, eliminating the chance of damaging the edge of the blade in question, it's the only way of really answering your question.
When my blades are stuck or hard to eject from the cart, I heat them with a Blow-Dryer for a minute or two, this usually loosens them from each other.
