A nutcracker comprises an upper endplate that includes a plurality of spaced apart apertures defining a central portion of the upper endplate and a lower endplate includes a plurality of spaced apart apertures defining a central portion of the lower endplate. A plurality of spaced apart apertures of the lower end plate is spaced relatively close together with respect to the apertures of the upper end plate. The elongated rods each have ends thereof pivotably mounted within a corresponding one of the apertures of the upper and lower endplates to define a tapered and compressible nut envelope. Each one of the rod members includes an inner end portion at at least one end thereof and includes a shoulder provided at a surface of the inner end portion for engaging an inboard face of a corresponding one of the endplates to limit axial displacement of the rod members.
