The Nutcracker, Sweet
This wonderful nutcracker is probably the simplest design I've ever seen. Ok, breaking a nut open isn't brain surgery, but this is a graceful solution.
Made from two small blocks of Beech wood, one has different size holes on each surface so that nuts of all sizes can be cracked. Place a nut in a hole, bang the blocks together, eat nut and repeat.
It’s a simple, efficient design which uses far less energy and materials to produce than any metal contraption. It’s $35 dollar price tag is a little high, but the finish looks great. If you’re handy with wood then you could knock one up yourself, and if not then you can grab one from the Museum of Modern Art's online store. ::MoMA
