Ive read the wiki on these razors, and I must say I dont really understand them. Ive read quite a few posts of how they are easy to shave with, and are good when you are in a hurry, but that makes them good for this situation? And what makes them easier to shave with? How does the blade attach to the razor? Our local woodmans grocery store has some Schick injector blades for sale, and it looks like they are in some sort of holder. Someone please help. I saw a bakelite Schick injector razor at the local antique store for $12, and it got me to asking these questions.
