Forged or stamped: how to tell in five seconds

Nearly every complaint about nail scissors — they tear, they fold the nail, they leave a ragged edge — comes down to one thing, and it is not sharpness. It is how the blades were made.

Stamped blades

A stamped blade is punched out of a rolled sheet, ground, and assembled. It is fast and cheap, and it works for a while. The problem is the geometry: two flat blades meet at one point and then drift apart along their length. Near the tip they no longer touch, so the nail is pinched and folded rather than cut.

Forged blades

A forged blade starts as a heated billet that is hammered into shape. The steel is compressed rather than sliced from a sheet, and the blade is left thicker along the spine and curved along its length. Assembled under tension, the two blades meet along their whole edge, from the pivot to the tip.

The test

Hold the instrument up to the light and close it slowly. On forged scissors the line of contact travels from the pivot to the tip with no gap showing. On stamped ones a wedge of daylight opens up before the tips meet. That gap is the tearing you feel later.

A second check: weight and balance. Forged instruments carry their mass near the pivot and sit still in the hand. Stamped ones feel light and tip-heavy.
