Stumpy,
The heads were forged out of used 1" tie rods, I was told that some rods are 1095, and these rods I have do harden good in water like 1095. They hold an edge well and are really tough. The handle material is red oak that I cut from my farm a couple of yrs. back, I was using osage orange but found out real quick that it is to brittle, the oak will take quite a bit of abuse much like hickory.
As for the weights, I don't know, I just cut off a chunk of tie rod
and start working to the size and shape I want, maybe Jerry can weigh them if he has a small enough scale, and post it.
Thanks Jerry for posting the pics.
Bill
