I am so impressed with this gadget. I was not expecting it to be worth much or even much help with my jewelry designing. I was definitely wrong on all accounts This is definitely the best tool for bending and shaping soft metal strips and wire. It comes with four pegs that are interchangeable. You place the pegs where you want them and it is like magic. So easy to make super designer jewelry. The amount of different designs you can do is amazing. The location you place the pegs are endless and produce a variety of shapes, including curves and angles. Half round shape at one end bends wire into large curves. Triangular shape at the other end bends wire up to a 90 degree angle. Aluminum body measures 4-3/8” x 1”. Includes two wood screws for permanently mounting on your workbench. It makes every day a lot easier to have this mounted on my work table is a life saver. I would recommend this to any jewelry designer whether you are a beginner or expert it is a must have. I purchased this to make my days easier and it is doing just that. It is made of a fine quality plastic that is heavy duty. The pegs are steel and will take all sizes of wires. Great for earings, bracelets, necklaces or key chains. You can buy this product with confidence.
