15 Everyday Objects With Features Most People Never Use

Most of us have been using the same handful of objects for years without ever stopping to inspect them. Fair enough: nobody wants to read the instruction manual for a stapler. But a surprising number of ordinary things have tiny features designed to solve problems we have simply learned to live with. The loose end of a tape measure is not broken, the little arrow on a fuel gauge is trying to help, and those extra holes in running shoes are not there for decoration. Some are clever safety details, while others are leftovers from uses we barely need anymore. Here are 15 everyday objects with features most people never use.

The metal hook shifts by its own thickness so the tape can measure accurately whether you are pulling it against an outside edge or pushing it against a wall.

The End of a Utility Knife Can Help Replace the Blade

On many snap-off utility knives, the removable end cap doubles as a blade snapper, letting you break away a dull segment and expose a fresh edge.

The uppermost eyelets on many running shoes can be used for a runner’s loop, a lacing method that holds the heel more securely in place.

The second, much smaller opening lets air enter as coffee leaves through the drinking hole, helping the liquid flow smoothly instead of awkwardly glugging out.
