I am a newbie and I just joined the site a few days ago. So far I am really impressed with quick responses and congenial attitude from this group. You guys have been awesome helping me learn more about DE shaving. I dove into the world of DE shaving after finding my grandfather's old razor in a medicine cabinet. I am not sure what type of razor it is. It can be broken down into three parts: the stem and two pieces to hold the blade. One of the two pieces has three prongs and the second has holes that fit over them. The blade is held by the three prong and not a line such as a Gillette speed shaver. No visible markings on its surface. I am posting pictures of it here. It works fine for me and since it's my grandpa's it's priceless in my mind. I'm just curious as to what type of razor it is. Thanks!
