Good vid on how to use an old Gillette OC. The OC Gillettes are some of my favourite DEs to use. They shave damn near as close as a Muhle R41 for me and because of that I would say it is an aggressive shaver which makes it an efficient shaver. I don't think you can have one without the other. I use a similar shallow angle with both DEs also and both operate in a narrow range as far as a suitable angle goes. I think that is another hallmark of an aggressive/efficient DE. You are definitely right that you really have to pay attention to what you are doing with the old OCs to be rewarded with a very fine shave. Thanks for posting this vid.
