I have two curved scissors at home, one is a grooming scissors and the other is a sewing scissors and both are really tiny but work really well.
I use the curved grooming scissors to trim my eyebrows, it seems to get around the hairs better than a regular scissors and I feel that it's safer too. I think it makes it less likely for me to poke myself with it. It's great that it's small too, really the perfect size and shape to care for brows.
The other one I use to cut stitches on clothing. Clothes that have been sewed with a sewing machine always have the smallest and tightest stitches. I've learned that the only way to cut and remove them is by using a curved scissors. The curve gets under the thread so easily.
Both of these are a must have tool for me at home.
