Sewing leather and leather-like materials may pose potential stitching problems.

A standard sharp round point needle may do a fine job sewing very thin soft leather materials.

For most leather a specialized cutting point achieves the best results.
 
Unlike woven or knit materials, leather dies not have an engineered structure.  Leather is the skin of animals that varies with thickness and density.   In the process of penetrating leather a round point needle will push into the leather until it bursts through.  The burst needle hole may be irregularly shaped.   When a needle sews cloth the needle holes contract after the needle exits the stitch holes.   When a needle makes a hole in leather, there’s no forgiveness after it exists the stitch hole.
 
Use a leather point needle with a specially shaped cutting point (shaped like a diamond, triangle, or wedge) will created a controlled shape hole that will enhance the appearance and strength of the stitched leather.
 
There’s a wide variety of leather points to achieve a particular stitch appearance, perform a required sewing task, and create appealing leather products or trims.
