I have a pair of Fiskars that I've used for many years. I don't use them often, but at one time I made a set of embroidered felt ornaments that had pinked edges. They were from a Vogue pattern, and I think that was my reason for buying the pinkers in the first place, in about 1978. They are great for preventing fraying when you pre-wash fabric. I also have the pinking rotary cutter, and that's fine for fabric prep, but if you do any garment sewing, the pinking shears are better for trimming curved seams.
I have definitely seen pinking shears in fabric shops within the last week.
