Wordlock

This has shown up a number of places (I got it off MetaEfficient), but it’s such a “why oh why wasn’t this invented earlier” thing that I have to post it: The Wordlock. A combination lock that uses letters to form words you are more likely to remember, and can be reset to another word at any time.

It also looks like it's way smaller than your average combination lock with a number spinning faceplate. It's only $5.98 from Staples and comes in colors.
