God made hard shell nuts and God made soft shell nuts.  This nut cracker made cracking them all equal.

I sell a lot of nut crackers.  My Kinetic Kracker (Electric Pecan Cracker) and Drill Cracker (for black walnuts and hard shell nuts) are leading nutcracker sellers on eBay.  I ship them around the world  Even so, sometimes there comes along something that makes me say, "Why didn't I think of that!"   This macadamia cracker is one of those items.

The lever-fulcrum action makes cracking the hardest nuts child's play.  It provides superior cracking with a minimal amount of shatter versus standard nut crackers by allowing the user amazing precision pressure control.  Apply easy pressure to increase cracking and reduce shatter (and shrapnel!)
