The clever hackers at Makezine came up with the cool, yet surprisingly easy, method for creating a Swiss Army Knife-style key ring as a much more efficient way to stash your keys in your pocket. I've seen a few of these for sale about, but all were crafted from aluminum and therefore limiting to the average DIYer. I especially like this design cause it uses easy-to-find hardware, and requirers no modification to the keys in order to make it work. Grabbing some really nice hardwood and spending some time with the finishing would turn this in a really clever and sturdy piece for everyday use.
