Schmetz Universal Machine Needles are a general purpose needle that can be used on knit or woven fabrics. It will do a number of tasks sufficiently. It has a long scarf that is great for zigzag stitching and it does not damage knits. It is sharp enough to go through many fabrics but it does have a slight ballpoint, so it is not ideal for going through many layers or high thread count fabrics. The chrome needles resists heat and wear, and will stay cool longer with less stitch distortion.
