Please can you advise what would be probably useful material to use for this tool. I am not tool maker I just like to make tools as in old pre robot and computer days. I had information about Dixons making it from a mild steel but after trying to make it from normal construction steel I had small off cut in the garage the result was horrendous. Too soft to have any meaningful use of it. If you can point me towards reasonable supplier of such material would be useful. I am adding link for part of the process. Thank you
