SCHMETZ 1738 LL — industrial sewing machine needles for leather

1738 LL, 16x230 TW are SCHMETZ industrial sewing machine needles with an LL-type angled cutting point. Designed for sewing leather when a straight, neat-looking seam is required. These needles are especially suitable for making shoes, bags, and other leather goods.

Features of the LL cutting point

LL (Twist Point) is a lens-shaped cutting point that makes a cut at approximately 135° to the direction of the seam. This helps create a slightly recessed, mostly straight stitch line.

LL and LR cutting points cut in opposite directions, so they can produce different-looking seams. The result is also affected by the direction in which the needle is inserted into the sewing machine and the twist of the thread.

Suitable materials and applications

• Various types of genuine leather.
• Leather shoes and shoe repairs.
• Leather bags, suitcases, and accessories.
• Leather goods where a straight seam is preferred.
