I am going to answer my own question.
As it turns out the hatchet that sits at the Fall River Historical Society very well may not be the weapon that killed Andrew and Abby Borden.
Blood does not 'stick' to metal but can be found on wood, which is why it is thought to be handless. That the murderer, prehaps Lizzie, discarded the handle that was covered in blood. But the problem is there are no traces of blood on the spot of the handle that remains. That is the spot where most of the blood would be as the handle itself would have the murder's hands over it.
Also it should be noted that a Dr. Frank Draper claimed, as in David Kent's book, "Forty Whacks", that on Abby's skull a small amount of metal 'gilt' was found. When hatchets are new that 'gilt' is there but wears away as they are used. He seemed to think the hatchet used in the slaying to be a new one. The Hatchet at the historical society is not new looking at all.
If this item was the murder weapon I think they may have been able to put Lizzie away. Because the murder weapon was never was found, I think it was one of the main reasons Lizzie was found not guilty. No witness, or murder weapon, just possibly a motive.
None the less, you have a very important artifact from the Borden house, most likely the most famous of them all.
