SPI (Acute Round Point) These Schmetz SPI needles feature an acute round point design, which is notably slim. This design allows for precise piercing of densely woven and coated fabrics, ensuring a clean seam appearance and minimizing seam puckering.

SCHMETZ SERV7 The SERV7 needle by SCHMETZ is engineered to address common sewing issues such as fabric damage and skipped stitches, especially when working with elastic materials. This needle is compatible with a wide range of needle systems and sizes, providing versatility across different sewing machines.

Key features of the SERV7 design include:

• Hump Scarf: Creates a larger loop of thread that is easily caught by the hook point, enhancing stitch formation.
• Blade Reinforcement: Provides superior needle stability, allowing the use of smaller needle sizes without compromising strength or durability.

With a 15% reinforcement, and up to 20% in some sizes, SERV7 needles are designed to be exceptionally sturdy and less prone to bending. This robustness helps to prevent damage to machine parts such as the hook or throat plate, ensuring a smoother sewing experience.
