Vintage Wiss Pinking Shears Scissors Serrated USA

Wiss Pinking Shears Scissors Serrated Scalloped Zig-Zag USA Right Hand Vintage Vintage. Approximately 9.25" long. Right handed pinking sheers. In working condition. Some wear off on handles mostly. These belonged to my Granny and she was an accomplished seamstress. She used these all the time. I am not sure how old these are but I am pretty sure I used these when I learned to sew in the early 70s. And she had them before that. See photos for details and measurements.
