BP0193 Diagonal Peen Hammer
by James Joyce
Talking about a blacksmith's hammer is about like talking of his dog, truck or wife. So, no matter what that style of hammer is called, Quarter peen, slash peen, Twisted face, Diagonal peen, Drawing hammer, or another name, let us be clear here, I am talking about MY hammer. Take what you like and leave the rest.
This is the view I see when I go to a blacksmith's demonstration when he is using a standard cross peen hammer to fuller. He pulls his off hand in toward the center of his body, aligns the working hammer hand and goes at it.
This is the view from the eye of the blacksmith doing the fullering. As you can see, as the standard cross peen strikes the work the blacksmith is essentially blind. His handle covers the view of where exactly the peen is striking.
Several years ago a blacksmith named, I think, Jeffery Foote (?) thought this an intolerable intrusion on his otherwise fine workmanship. Jeffery told me he took a Swedish cross peen, heated it up, twisted the peen 45 degrees. He opened the world of blacksmithing to a new dimension of accuracy. And introduced the diagonal cross peen hammer to artist blacksmithing.
When a right handed smith uses a left diagonal pein hammer, smith�s view of his fullering strike location is impeded with the diagonal cross peen hammer.
When the right handed smith used a right diagonal pein, the smith�s view of his fullering strike location is no longer impeded with the right diagonal cross peen hammer.
When the left handed smith used a left diagonal pein, the smith's view of his fullering strike location is no longer impeded with the left diagonal cross peen hammer.
But when the left handed model of the diagonal cross peen is used by a right handed smith, it becomes a diagonal straight peen, again allowing an unimpeded view of work (his arm is now to the side) and producing greater accuracy and smoother work.
This shows the body position of the smith fullering at the horn when using the diagonal cross peen. He has relaxed posture, with the natural hammer arm position at his side. Notice that from this position he can pin the off hand to his left side for easy control of the work piece.
This shows the same smith forcing his arms into alignment in front of his body to fuller over the horn with a standard cross peen hammer.
I hope this helps explain why many of us blacksmiths (like Rob Gunther and Bill Epps, to name just 2 you probably know) have switched over to diagonal peen hammers for better control of our work.
A full set of smithing hammers should include a right and left as above, a cross peen, a straight peen and a round face spreading hammer, all of the peens should have at least a 1/2 inch rounded face so as not to make sharp dings in the material worked.
