Welcome aboard. Many of us are new to or have recently returned to DE shaving. We can all learn together. There are some really great guys here to learn from.
Welcome @jamesrw30. Like you, I am new here and looking forward to learning from those who have more experience.
Welcome to TSD! How fortunate you are to have your grandfather's razor. It always makes shaving extra special. We are still waiting for some pics of the razor!
