Also called a pelican scissors by some.
Appliqué is a fun way to upgrade clothes, patch, or cover stains.
When doing appliqué, you typically sew the outline with thin stitches first, often on a sewing machine, and then trim away the excess fabric close to the seam, before covering the edge with tight zigzag stitches, for example.
The "beak" of these scissors acts as a wedge between the garment and the appliqué, making it easier to get close to the seam without risking accidentally cutting holes in the garment. If you enjoy patching and appliqué, this is a great tool for you!
