A great pair of Beadsmith bail making pliers. They come with two non-graduated cylinders so perfect for making loops, bails, ends and connectors (see image 2). Here you get two different cyclinder sizes: 1.5mm and 2mm (diameter). As these ones are so small, you can also try making your own jumprings with them. Simply wrap some wire tightly round one cylinder, remove the coil and snip up the middle with some wire cutters.
They have a spring action, which reduces hand fatigue, and a lapjoint construction.
