Take 2 Nutcracker Naomi

The Noami nutcracker cracks nuts using a coiled spring with a striking pin inside. Cracking a nut is very simple: place a nut on the metal plate, place the spring over it, and hold it at the bottom. Then pull the spring up by the ball and release. The striking pin will shoot down and crack the nut, while the closing spring also prevents bits of shell from flying around.
