Do you hate carrying around a jumbled mess of keys? Sure, slapping them all on a ring is the most simple way to carry your keys, but it’s not very well-organized, nor is it all that appealing to look at. If this bothers you, then why not craft a better solution? That’s exactly what one Instructables user did.
Using a hex key set, a few extra bits and common workshop tools, you can make a really neat key holder. The most difficult work is grinding down the heads of each key so that they fit smoothly to the contour of the holder. Once they are on, all you need to do is flip out the key you need, unlock something, then fold it back where it was.
