Civil War Era H Boker Bone Marrow Tool 21 3/4" Long I was told this is a Civil War era bone marrow tool. I'm not sure if this would have been used on humans or animals. This is stamped H Boker on one side. It looks like some light initials on the opposite side. This measures 21 3/4 inches long about 9/16 to 5/8 inches wide and is curved as you can see. This is made of steel. Look at the photos to judge the condition for yourself.
