This is amazing. A guy called Brett undertakes all sorts of projects and documents them in a blog called Project Blog. And he decides to make a double edged safety razor. So he sandwiches a blade between two pieces cut out of PVC tubes and holds it all together with a long nut and bolt, which also serves as the razor handle. And it works and he is shaving with it.
Obviously it didn’t just bolt together and work straight off, he spent 2 to 3 hours fettling it. But the materials cost him $1. Another blow against the multinational shaving industry. He could buy Supermax blades for just over 2 pence each and then he would have the ultimate in bargain DE shaving!
