A nutcracking unit which is adapted for use in a high production nutcracking apparatus of the type wherein a nut is held between an anvil and cracking die, and a shuttle then impacts against the rear end surface of the cracking die to sharply advance the cracking die and thereby crack the shell of the nut. The cracking die and the anvil have opposing concave cracking surfaces for supporting a nut therebetween, and each of the concave cracking surfaces is defined by an outwardly bowed convoluted curve made with circle arcs when viewed in cross section. This configuration allows a relatively small nut, such as a pecan seedling, to be engaged and cracked at a point spaced from the pointed end of the nut, which in turn results in fewer uncracked or insufficiently cracked nuts.
