My own tool collection is modest and consists largely of the inexpensive variety. Until this craft starts to pay off, I can't justify the expense when money is put to better use buying materials (Christmas is coming and you never know what Santa will bring – Lindstrom, hint hint). But every once in a while I succumb to the lure of a new tool. After hearing about these things on a certain website and watching them be used, I thought I'd give them a try, especially after it was pointed out that using these specialized pliers would cut down on wire waste. Love that.
With these I can standardize coil and loop sizes more effectively. I can make a single ring without having to waste precious inches (even though I often use scraps to make clasps, hooks, eyes and charms I still hate it). They're also easier on the fingers when bending half-hard or heavy gauge wire. They look a bit ungainly, but you use them like ordinary round nose pliers with the wrapping jaw furthest away from you (I've shown them here at an awkward angle so you can see the wire looped inside). The inner jaw, the holding jaw, is shielded by thick plastic on the large ones to avoid marring soft wire like pure silver. A thoughtful touch.
I bought them in 3 sizes, the two largest primarily to make rings for fusing, and the smallest to make jump rings and split rings, so often needed with heavier pieces and sort of a pain to make with round nose pliers.
The largest makes sizes 20mm, 16mm and 13mm, the medium makes rings in 10mm, 7mm and 5mm increments, and the smallest 5.5mm, 3.5mm and 2mm. So far I like working with them and keep finding new uses for them (like earwires). Those Sharpie markers might just go into retirement.
