Okay....I have been bit by the injector bug! I bought a hydromatic on the trading site nearly a year ago and finally got around to using it and I am hooked!! I have a question for those of you much more experienced with the injectos. In my quest to find more injector razors, I keep seeing the adjustables for sale. Can anyone explain the purpose behind these? I am assuming it's like the adjustable DE's in that it changes the angle of the blade to make it more "aggressive", but that is just conjecture on my part. Thank you for your input!!
