I've come by these pieces of steel separately but both times was with other blacksmith items. I think I've seen these shapes elsewhere too but not sure what they are. The square ends are 1"x1' and 1 1/4"x1 1/4" and they are about 5" long.
At 1st I thought they must be just random chunks of steel but because I have 2 of them and I think I've seen others in the past I'm thinking they must have a purpose. Any ideas?
