For the sole purpose of safety, protection and to keep something private, locks were invented to shut doors and things. They have been created in boring, plain, mechanical vogue appearance, with no thought or care to the art world.
Good thing is that, nowadays, there have been many crafts and designs of locks that will make a locksmith proud to say he is part of the world of locks. Decorative and fancy looking locks create a different and nice look on plain doors and houses. Some designs also compliment the furnishings in the house.
Art and creativity have improved the appearances of the very useful locks. And these enhancements seem to boost sales. Truly, the craft of the locksmith is now an artwork in itself.
Unfortunately, the great improvements of locks still don't mean that once you have it, you are guaranteed to be safe, especially if you are not using it the right way. Locks should be locked to keep you safe and secured. Neglecting or losing keys can pose threat. Anyone who has them can open your locks anytime they want to.
Therefore, one should always remember, no matter how fancy looking your lock is, no matter how great the quality it is, it will render useless without proper care and use.
