Only way to do shanks, too time consuming to make them ready for the grinder. I cut each shank into about 3 pieces with either a bone saw or sawzall with a coarse blade. Also cut the blade in half and make two more roasts. I prefer to slow braise in the oven in a porcelain cast iron crock pot. Sear it good with seasoning and then add liquid of choice and braise for 4 hours or so. Can smoke first to add a different flavor. Connective tissue just disappears and bones just pull out. I've done it with elk ribs also.
