What is the metal or plastic end of a shoelace called?
Aglet for which they manufacture aglets. Many companies prefer to add metal sheaths over plastic aglets for the sake of durability. Some may add logos or pictures to show that the shoelaces are their own products. Aglet An aglet ( ) is a small sheath, often made of plastic or metal, used on each end of a shoelace, a cord, or a drawstring. An aglet keeps the fibers of the lace or cord from unraveling; its firmness and narrow profile make it easier to hold and easier to feed through eyelets, lugs, or other lacing guides.

Shoelace formula Shoelace formula The shoelace formula or shoelace algorithm (also known as Gauss's area formula and the surveyor's formula) is a mathematical algorithm to determine the area of a simple polygon whose vertices are described by their Cartesian coordinates in the plane. The user cross-multiplies corresponding coordinates to find the area encompassing the polygon, and subtracts it from the surrounding polygon to find the area of the polygon within. It is called the shoelace formula because of the constant cross-multiplying for the coordinates making up the polygon, like tying shoelaces. It is also sometimes called the shoelace method. It has applications
