Remember this? Also called the Cubist Nutcracker by some, this nutcracker by Adam and Harborth does the job in a straightforward way. Place a nut in an appropriately sized indention in the larger cube, take the other smooth cube and place it on top of the nut and then give it a good whack. Voilá, the nut is cracked.
