Hello all.. I decided to register after being a lurker for a long while.... I have a question. I currently use an old Gem Micromatic open comb to shave the forest known as my beard. I love this thing and would never switch to anything else (i also have a couple of DE razors but the blades seem to flex to much under my beard). I wanted to find out if any one has had experience using SE PTFE coated blades from medical supply sites like tedpella? I could get 200 blades for about $35 but i know that they are not cut exactly the same as the store bought blades and i did not want to sink that much money into useless blades. Any advice would be appreciated.
