Any feedback regarding ring bound and mushroom head handles.
Anything else you would consider I would order at the same time a splitting froe, draw knife/rounded draw knife, I see the carpenters axe some people say they use them others never use.
All great tools in and of themselves. If they are right for you depends on the nature of the work you do just like any sensible advise would.
It seems the kind of steel used is particularly important to you but this is only part of what makes a good tool. Equally important is what the smid is capable of doing with that material. In particular the subtitles of the heat treatment and this depends on knowledge and experience along with a keen intuition of the smid. So, I would say when going the custom made route you ought to have a relationship with the one doing the work, otherwise stick to more standard or well-known products.
