An antler tool is used to notch a stone flake to give it a saw-like serrated edge that can be used to section bones. Bone spear points are made of the lower leg bones of deer. A stone tool blade with a chisel-like end is used as a graving tool to section the bone to get the right piece for making a spear, or removing a piece to make a bone wedge that is further shaped on a hard stone.
