The 134 LR FHS needle (needle system 134) has a right cutting point (45°) for working leather, synthetic leather and other coated materials – never for woven fabric, since the cutting action would sever the weave threads. The FHS version allows sewing without hook adjustment. It is used in industrial sewing machines for leather and synthetic-leather work, where the cutting point produces a clean puncture. Suitable machine classes are found, among others, at Pfaff (classes 1243, 2081-731/…, 2081-748/…, 2083), Dürkopp Adler (classes 271-140332, 271-140332-01, 271-140342-01, 272-160362-01) and Juki (classes DDL-5550N, DDL-5550N-7, DDL-5550NA, DDL-5550NA-7).
Thinner needle sizes are used, among others, for thinner to medium-weight leather, and the thicker versions for medium-weight leather for everyday leather goods and saddlery work. As sewing thread, a bonded polyester or nylon thread such as Amann Serabond, Amann Strongbond or Coats Dabond is usually recommended, in a thickness matching the needle size chosen. A cutting point is required here to create clean puncture channels in firm materials.
