Abstract
The present invention relates to an impact nutcracker of the type having an anvil and an impact member aligned but spaced apart wherein the impact member and anvil are adapted to hold a nut therebetween. A striking device is provided to transmit an impact force to said impact member which transmits the force to the shell of the held nut, causing the same to be cracked and broken such that the kernel can be easily and conveniently removed. The present invention entails an improved impact nutcracker for cracking hard-shell nuts such as black walnuts and macadamia nuts. In order to achieve this, both the impact member and anvil is provided about inner face-to-face end portions with a nut receiving recess that is specifically shaped in a shallow and slightly rounded form to directly engage and surround a substantial portion of the hard-shell nut. This substantial direct engagement of the nut enables the nutcracker to crack the hard-shell nut in a manner that generally leaves the internal kernel mostly unbroken and undisturbed.
