Claim:
A nutcracker comprising: a vertical cylinder with a textured interior surface made from a single rectangular piece of tread plate, wherein the vertical cylinder comprises an opening with a spout extending from the bottom of the opening; a conical member with a textured exterior surface made from an arced piece of sheet metal welded together to form a conical shape, a first circular piece of sheet metal welded onto the conical member to form a narrow end, and a second circular piece of sheet metal welded onto the conical member to form a broad end; a rod extending from the narrow end of the conical member; a rod extending from the broad end of the conical member; a cross-arm bearing support connected to a top of the vertical cylinder, wherein the cross-arm bearing support is connected to a first bearing which is configured to receive the rod and allow the rod to spin within the first bearing; a first plate slanted from a horizontal plane and connected to the vertical cylinder, wherein the first plate is configured to receive the rod and allow the rod to spin within the first plate; wherein the conical member is vertically centered within the vertical cylinder when the bearing receives the rod and the first plate receives the rod so that: the textured exterior surface and textured interior surface form a cracking zone with a minimum distance between the textured exterior surface and textured interior surface between seven-sixteenths and one-half of an inch, and an angle between the textured interior surface and the textured exterior surface is eight degrees; and a second plate attached to the vertical cylinder below the first plate and being connected to a second bearing which is configured to receive the rod and allow the rod to spin within the second bearing.
