The KAI S-4 - 4 in (10cm) Needle-craft scissor is sharp, with pointed tips that allow for detailed cutting and trimming.
Very popular for trimming threads, hard-anger embroidery, bead work, rug hooking, and fly tying for fishermen.

The proper way to use appliqué scissors is to insert the duckbill side of the blade between the fabric you want to cut and the fabric underneath that will remain uncut. This enables you to cut the appliqué fabric close to the placement stitching without inadvertently cutting the fabric underneath.  The duckbill will be underneath the pointed blade with the duckbill between the appliqué fabric and the background fabric and the pointed blade on top of the appliqué fabric.
