Scissors go dull both where the edges wear and where the pivot stops holding those edges together.
When the purchase is complete, return to the original window. It will refresh.
Scissors dull at the blade because the edges chip, roll, or wear flat, and they also go dull at the pivot because the joint wears until the blades no longer press together as they pass. A keen edge that cannot meet its partner cuts no better than a blunt one. The opening covers edges chip, roll, and wear, highest force sits near the pivot, and a loose joint lets blades miss.
