The # 2 Conner Pliers are especially helpful to set or tighten side stones in a basket setting as well as on other type mountings. One side of the pliers has a slot for the wire under the stone and the other side has a beading tool cup on it. Also great for setting earrings! Simply slip the post through the slotted side and bring the beading tool down on the prong making this type of work much quicker and easier. Perfect for setting and tightening accent diamonds surrounding color center stones. Great for earrings, with or without underbezel wires. This plier has the equivalent of a # 20 beading tool tip. If you need a larger tip, you can just use a ball bur to enlarge the size. If you need to make it smaller, just sand down the inside of the jaw. You may need to file the outside tip down to get the cup closer to the edge.
