Leather needle has the shape like a wedge at the point which gives it superior piercing power for unyielding fabric such as real leather, suede or heavy vinyl. This needle makes a clean, large hole as it enters the fabric. It is better to tie or seal thread ends rather than backstitching to secure. Sew accurately since removing stitches and restitching will leave hole markings. Synthetic leathers and suedes can and should be sewn with standard needles.
