I specifically remember my mom getting mad at my dad for trimming his toenails with her "good" scissors.
I've always had my sewing scissors and used other scissors for other tasks.
Not only do you need a sharp pair of scissors, you want the blades to meet in such a way that they cut straight. I've noticed that not all scissors (regardless of price) will cut straight. Also some scissors are too loose or too tight to cut well.
So as you can see I'm another picky scissors user!
