|I have Gingher pinkers and also my old standby Fiskars. I have had a few pair of the Fiskars because it seems they are always tempting to use for things other than the woven fabrics for which they are designed. When my pinkers get to the point where they are not working well on much of anything, I discovered that if I quickly cut through 4 or 5 layers of aluminum foil a few times, that it brings back their edge a little, at least enough to use them on paper. I hope this might work for you before you throw them out. Of course, there is nothing like having them professionally sharpened.
