This needle is made for sewing hard, thick or heavy materials. It will sew through multiple ply applications like quilting, jeans, applique or heavy embroidery. It is actually an industrial needle with a flat shank. If you are bending or breaking 15x1's this needle could solve your problem. These hard chrome needles will outlast a standard 15x1 and the PD/titanium needles are even more wear-resistant. They are available in either sharp or ball point with a hard chrome or PD/titanium finish.
New announcement from Schmetz below! You will know they are chrome needles because it will be listed on the package. Coming late 2021!
