線材成型鉗 — 圓扁嘴，附可更換尼龍夾頭，適用於串珠工藝

Swapping the nylon jaws takes about ten seconds and they leave zero tool marks on my copper wire. The round nose gives me consistent loops every time, even on 20-gauge. My bead wrapping finally looks clean instead of scratched up.

I do a lot of wire-wrapped pendants and the round nose finally gives me consistent loops instead of the squished ovals my old pliers made. Swapping in the flat nylon jaws for bending keeps the wire from getting chewed up too.
