Thanks for the replies I do have a forge, I took a class at NAIT with Shawn Cunningham. In that class we made a hammer but it was pre shaped, the only thing we had to do was widen the eye and round the face, anyway that tongs and a punch.
I don't know the metal that was used then but when we had the hammers at non magnetic with put the faces in water and would rotate when the water evaporated on the opposite face, we then used the OA torch on the eye till we saw a brownish purple starting to appear on the face then quenched it again.
I just didn't know how I would go about it without the OA
