I wouldn't discount anything that has lunch hidden inside, but I'm particularly fond of this sharp, functional, and 100% handmade lunch tote project. This cool how-to comes from Mr. Lentz, a Southwestern U.S.-based craftsman who calls himself a "modern cowboy of the creative revolution."
The design features a continuous full-grain leather top, bottom, front, and back, with some lightweight pine sides that keep everything rigid, and prevents your lunch from flopping around. Everything's held together with brass screws and snaps, and I'm digging the mixed-media look on such a practical object.
