環形成形與光學作業 — 圓頭鉗，方形手柄，不鏽鋼，120 公釐

I was skeptical about the square handles, but they really do stop the pliers from twisting in my hand when I'm rolling a tight loop. The stainless steel feels solid and the 120 mm length gives good control for detailed work.

Finally, a pair of pliers that doesn't slip sideways when I'm rolling a loop—the square handles press into my fingers just enough to keep everything steady. The stainless steel feels solid in the hand, and at 120 mm they're a perfect size for detailed work without cramping.

The square handles really do stop the tool from rolling in my fingers — I can finally tighten a jump ring without it slipping sideways. Made a dozen loops this afternoon and every single one stayed perfectly round. Exactly what I needed for delicate wire work.
