A keychain (also key fob or keyring) is a small ring or chain of metal to which several keys can be attached. The length of a keychain allows an item to be used more easily than if connected directly to a keyring. Not only will a keychain allow you to keep track of where your keys are, but it will also keep your EDC secure and far away from pickpockets. There’s really no reason not to own a keychain! A key ring is a metal ring which you use to keep your keys together. You pass the ring through the holes in your keys. A key is a piece of metal that fits inside a lock and turns to open it. You might have a key ring with a house key, a car key, and maybe several more keys. A key is typically cut from metal, although many hotels use plastic keys for their guest rooms. A key is a specially shaped piece of metal that you place in a lock and turn in order to open or lock a door, or to start or stop the engine of a vehicle.Most keychains are made from either plastic or metal. However, they can also be made from fabric, paper, wood, or rubber. Think of a lucky rabbit’s foot or those flimsy #1’s that were popular in the 90s. With that in mind, there’s no right way to make a keychain. But you also don’t want to spend a ton of money on items that seem nice but have no practicality. Keychains are practical and cheap to make. Everyone needs keychains, so you know these promotional items won’t end up in the garbage, even though they are cheap to buy. The original keychain fastener was used to prevent burglaries, by fastening keys tightly to doors. The invention was patented in 1894 by Frederick J. Loudin. As well as an inventor, Loudin was a member of the Jubilee Singers, a world-famous touring African-American choir who performed for Queen Victoria.
