This is my Homemade Bradawl I made a few days ago. I used a Teak coffee table leg for the handle that I turned on my Homemade lathe, Then a piece of copper water pipe for the collar and an old screw driver for the spike that I ground down to shape on my bench grinder. I then found a piece of hollow Alloy pipe that I cut to size and buffed it out on the lathe to use as the safety sleeve. . I was very happy with the end result.
