I like the decorative effect that keyed miter joints lend to an otherwise simple box. But they also add a great deal of strength to a notoriously weak joint. Here’s a quick slideshow on cutting and installing keys in miter joints using a very simple jig featured in the August 2012 issue of Popular Woodworking Magazine. You’ll also find a box I made using this technique in an article called “4 Boxes, 4 Ways.” In the same article you’ll find three other boxes – some of our editors’ favorites.
