A stitching awl is a tool with which holes can be punctured in a variety of materials, or existing holes can be enlarged. It is also used for sewing heavy materials, such as leather or canvas. It is a thin, tapered metal shaft, coming to a sharp point, either straight or slightly bent. These shafts are often in the form of interchangeable needles. They usually have an eye piercing at the pointed end to aid in drawing thread through holes for the purpose of manual lockstitch sewing, in which case it is also called a sewing awl. Stitching awls are frequently used by shoe repairers and other leatherworkers. Sewing awls are used to make lock stitches. The needle, with the thread in the eye is pushed through the material. The thread is then pulled through the eye to extend it. As the needle is pushed through the material, the extra thread from the first stitch is then threaded through the loops of successive stitches creating a lock stitch. The action is likened to that of a "miniature sewing machine". Styles may vary, as they are adapted to specific trades, such as making shoes or saddles. They are also used in the printing trades to aid in setting movable type and in bookbinding.
When he was a child, Louis Braille gouged his eye with an awl by accident. One eye was destroyed instantly, and a subsequent infection later claimed the other eye, making him blind by the time he was four. The accident spurred Braille to the invention of the Braille alphabet.
In terms of nomenclature French Canadian fur traders in the late 18th or early 19th century called one band of the Salish peoples of the American Northwest as Coeur d'Alene meaning "heart of an awl," in reference to their savvy in trading. British traders and later colonists adopted the French term for the people, which eventually became the official name of the tribe.
