As I understand, Gingher doesn't put the serrated edge back on the scissors any more.
The owner of the shop where I work has been sharpening scissors since he was 16, and is now 54. And he still just charges $1, or $2 for pinking shears. However, he has turned away the specialty scissors, because he can't put the serrated edge back on. And if the tip isn't cutting, he'll round it off. Sometimes they need bending or tightening or oiling, as well as sharpening, and he'll do that, too, for the same price.
