I would love to have a pair of Ginghers, but I bought a pair of Fiskers about 30 yrs ago when I bought my machine, have used them for everything that I have done. Granted I am not a sewer, but I have never had them sharpened and did do some sewing yrs ago. Now of course all quilting so you don't use scissors much.
I just go down when they get dull and buy the cheapy ones and Joanns. I have them all over the house on those things you can put around your neck so when I sew they are right there. I do have a pair of finger nail scissors that I love, now they are sharp, but got them for free and use them also for Applique. I see a lot agree with me, good luck.
