I use only Gingher scissors for anything that has to do with sewing. I've had my Gingher's since about 1981. Never had them sharpened and they are still as sharp as a razor blade and I have done quite a bit of sewing in the past 50 years. I do cut my batting with them. I do not cut my batting with rotary cutters.
I just found out over the week-end that Gingher has a rotary cutter. Joanne only had a left handed pair. I can't wait to get one.
What's the real answer.........
