A very slim needle with a thin shaft that helps make very straight stitches. It was developed for the modern micro- fibers and polyesters and high thread count, high quality fabrics used today. The point is very sharp thus the name but because of this it is a bit more fragile and needs to be changed more regularly. This is a great needle for piecing high thread count fabrics like Batiks, silks, and microfibers. It is also used for beautiful topstitching or edge stitching. Size 80, 5 per package.
