Abstract
A manually operated nutcracking device with a threaded member for urging a carrier and a wedge thereon into nut engagement to split the nut. A base includes a pair of guides and a nut supporting surface. The carrier includes plate components coupled to the wedge in a detachable manner. The plate components are recessed to engage the inner edges of the pair of guides. A foot on the threaded member imparts travel to the carrier. The nut supporting surface area on the base has convergent surfaces for retention of a nut during cracking. Concave surfaces formed in the convergent surfaces are for retention of a nut with a circular shell.
