A vacuum-assisted nut cracker having a main chamber with a hard target that cracks nuts is described. A motor driven vacuum pump draws a vacuum through the main chamber and through a suction pipe. The air sucked into the suction pipe draws shelled nuts up the suction pipe. The nuts pick up momentum and fly out the suction pipe onto the hard target, causing the nuts to crack. Shell and cracked nuts drop down and are subsequently collected. Various methods can be used to regulate the air flow, and thus the induced nut momentum. Shelled nuts can be fed into the vacuum-assisted nut cracker either by hand or by locating the nozzle adjacent a pile of nuts.

A hand-held inertia nutcracker for removing shells from a variety of nuts. The nutcracker having multiple configurations according to user preference. The easy to use device allows for easy insertion of nuts and quick removal of the nut and shell material. The nut is automatically centered in the cracking chamber as it is inserted so that consistent performance is achieved. The nutcracker also automatically adjusts for a variety of types and sizes of nuts without operator intervention. The design allows for rapid repeatability in use, thereby taking most of the effort out of extracting the nut from the shell.
