The needles have a burr-free and stamped eye. Their polished tip is fine and slender, and together with the smooth surface, they glide through all fabrics. Furthermore, the matched spring hardness allows for smooth operation without bending or breaking. Typically, the long needles are about 7 mm longer and are used more for common sewing tasks due to their better grip. The half-long needles, favored by experienced users, are often chosen for more demanding sewing tasks; their quicker penetration makes them just right. The shape of the needle head allows for easy handling without a thimble.
