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. The shank(top part) of these needles have one flat side and one rounded side. These will fit all "household" models of Brother, Janome, Singer, Pfaff, Bernina, Viking, Elna, Kenmore, Baby Lock, Simplicity, Necchi, White and many others.These will fit all "household" models of Brother, Janome, Singer, Pfaff, Bernina, Viking, Elna, Kenmore, Baby Lock, Simplicity, Necchi, White and many others.
