My largest cutting scissors,
I love my razor edge Fiskars with the storage sheath.

For mid midsize sewing scissors,
I LOVE my Havel's. I have the 5.5" length both flat and curved. And the bonuses are the serrated edges and the large finger loops. SUCH a help when you are trying to make fine cuts.

For my small scissors.
The ones that I keep at my machine - affixed by a magnet - are the purple handled appllique scissors. They are 4" long and 1" blades. The best prices I have found are at Connecting Threads.
