This is the greatest tool for teddy bear and dollmakers! it is a mini cotter pin turner. It is used to make it extremely easy on you when you're making a smaller bear with smaller joints and smaller Cotter pins. It will get right in between the gap of the cotter pin and turn it extremely easily in a small spot and give you a tight turn! Makes for the best joints! I actually have two of these and they are in brand-new shape in original packaging! Please Convo me with any questions.
