OK I have to get something off my chest. Every time I see someone shaving on YouTube I notice the wide angle of the blade against the skin. The blade is closer to perpendicular to the skin than parallel with it. Let's call it a >45* angle.
When I shave my blade rarely breaks 45*, if ever. Frankly I'm usually less than 30*.
Am I doing this wrong? If so it has been yielding good results for 10 years or so...
