I have been looking for quite a while, trying to locate a type o injector. I believe I have one located in Japan, but wanted to know how the shave differed from earlier models like the type L I am currently using. Ironically, I had a type o and used it regularly until five years or so ago, when I inexplicably lost it. I wasn't into wetshaving at that time, so I want to get it back. Anyone with type o usage as well as context for comparison greatly appreciated.
