There are many methods of hardening and tempering and many arguments of how to go about doing it.
That is my method and it has never failed me, it is a simple method which makes a simple tool that is all you require for this project.
No need to do it to masonry nails they are already hard enuff just grind the head off and shape and sharpen.
Make a handle or use a watchmakers vice for very good results init?
