What is "wordlock"

Wordlock is a brand of combination locks, made by Wordlock, Inc., that differs from traditional combination locks in that it has letters on its dials instead of

numbers. This allows the combination to be a four-letter or five-letter word or name, similar to a password, and therefore potentially easier to remember than a series of digits. Wordlocks come in luggage locks, bike locks, padlocks, cable locks and commercial locks.
