I used to use the Gillette Fusion ProGlide for years, however,with the ridiculous prices I finally decided to switch to DE. For the past month I've been using the Parker 99R & most of the blades I've used (Astra Blue, Astra Green, Voskhod, Gillette Platinum, Shark, Derby) all do well on my face, but I'm getting irritation on my neck. It seems I get nicks and cuts around my jawline where my neck begins. I've been using Pacific Shaving Company products & haven't tried using a brush or shave soap yet. I've heard using a adjustable DE razor might help. I'm open to trying other techniques & products that might help fix my issues.
