i have. actually i use some in conjunction with steel hand tools, theres just placxes that a round piece of sand stone fits better on a limb with character than any file or knife, or rasp does.and yes occasionally a belt sander. lol most my arrows are made from natural materials with natural materials. a number of years ago there was a fella named Jamie on here who made a elm bow with all stone bone ect tools. it inspired me so i made a ash bow with like tools. as long as you work it green no problem. i still kind of remember his post about how hard working the elm was, hence my thought of using a ash sapling. lol anyways, yea give it a shot. it takes a little bit of time. but its not like work unless you make it that way. i enjoyed making that ash bow little by little.
