製作扣環與繞線鉗 — 大型橢圓心軸 12×8mm 與 9×6mm，珠寶

I was getting so frustrated with uneven loops on thick wire, but the 12×8 mm mandrel on these pliers finally gives me consistent, perfectly round bails every time. The larger size makes a noticeable difference when working with heavier pendants.

My 9×6 mandrel keeps spitting out perfectly uniform ovals every single time—honestly, I've stopped measuring my loops altogether. The larger 12mm jaw handles chunky pendants that used to make me wrestle with two pairs of pliers.

The 12 mm mandrel finally lets me make a bail that actually fits over a thick cord, and the shape stays perfectly consistent every time. I’ve used it for a dozen pendants this week and haven’t had to rework a single loop.
