A very slim needle with a thin shaft that helps to make very straight stitches. It was developed for modern micro-fibers and polyesters used in the high-thread-count, high-quality fabrics like batiks, silks, and microfibers. It is also used for beautiful topstitching or edge stitching. The point is very sharp, thus the name, but it is a bit more fragile and needs to be changed more regularly. Size 80, 100 per package.
