I am sure I have over 20 pair of scissors...haven't counted them though. I have Fiskars...the ones with the springs..they are easier on my hand for cutting....I have them in the small size, full size, and pinking shears.
I have Ginghers in the full size, embroidery size, and applique scissors. I have Dovos in many varieties...they are so sharp....at least 4 of them. I have several pair of paper scissors. I have a couple pair of scissors I got from my MIL when she passed away.....not sure what kinds they are. I have several pair of cute small embroidery scissors-like cats, patriotic. I have other different scissors that I have bought over the years-don't remember the brands now. Also have kitchen scissors.
Oh, you asked the top 3....my full sized Fiskars, my Ginghers, and a Dovos pair with handle I really like.
