Another interesting detail about the oversized flaker is that the cylinder of antler was simply hammered into the hole. There is no lashing. Antler is like a super durable plastic that is given to compression. My guess is that by hammering the cylinder down into the hole, it squeezed the antler. And, the tension created from the squeeze appears to create a great deal of static friction. As a result, it seems to be immovable.
For all of the people interested in how Native Americans made their points, there is evidence to suggest that when antler cylinders were found accompanying the graves of deceased flintknappers, there was usually "one" cylinder per grave - not two, three, or four. And, in at least one case, the cylinder was found over the pelvis area. My guess is that the cylinders are probably found laying to either the left, or the right, of the pelvis, and facing away from the body. Or, the cylinders may have been found parallel to the body, in the pelvis area. My guess is that the cylinders are not found dead center over the pelvis. If my theory is correct, then there would be a reason as to why this is.
