I have LOTS of scissors, and I do have my favorites. Fiskars are well made, and unless they have been abused, they stay sharp for a long time. Bonus: they are easily sharpened. Kai scissors are wonderful, but sometimes hard to find. Ginghers are probably the easiest to find great scissors; they have so many styles that you can surely find a pair to suit your purpose, whatever it is. Wasa scissors are hard to find, but probably a little higher quality than Gingher. Bohin scissors are great, but since they are from France, they are always expensive, and extremely hard to find.
My absolute favorite scissors, though, are DOVO. They are made in Solingen Germany, where lots of top quality blades are made. They are incredibly sharp, have great points, but they have something more--they are so smooth to use that you feel like you are using a luxury instrument. They are hard to find, and they are expensive--but worth every penny!
