I usually like them with a wider bit too. I think he was replicating an original I would ask but he just got out of surgery 2 hours ago and im not sure he could comprehend the question lol
A lot of originals had a steel bit wrapped in iron or an inferior steel. I think it makes a better head than all steel since it has a bit more give
he made one very similar to that several years ago except it had a spike on the back as well unfortunately it was stolen by the neighbors shortly after he finished. The neighbor insisted he made it even though it had my dads makers mark and my initials burnt into the handle
