Beef leg bones, middle pic is fresh , seems to be a bit stronger , not as brittle, the natural oils still in it, the two outside are sun bleached, thicker but feel brittle to the touch, unweighed as of yet but to my hand slightly less than steel broads about the same as stone, will weigh them soon , i have made bone points and blunts before and tested them on trees ..lol..if they can penetrate wood at 10 to 15 yrds most assuredly gonna go through flesh. Will get back to yall with final weights.
