1. A bone sectioning tool for severing the rib bones of vertebrate fish without damaging the flesh, comprising:

  • a frame;

    an elongated arbor shaft rotatably mounted to the frame;

    a plurality of circular saw blades mounted to the arbor shaft for coaxial rotation therewith;

    spacer discs on the shaft between adjacent saw blades for spacing the blades substantially equally apart, and wherein each disc has a diameter slightly less than the diameters of adjacent saw blades;

    wherein the saw blades and discs are of varying diameters and are arranged on the arbor shaft increasing in diameter toward the longitudinal center of the arbor shaft to complement the cross-sectional curvature of the splayed sides of an eviscerated vertebrate fish and to substantially limit the depth of cut of the blades;

    leaf spring members between adjacent blades and adjacent the blade periphery for preventing binding of rib bones between adjacent blades and for preventing the blades from substantially penetrating into the flesh while severing the bones; and

    drive means for rotating the shaft and blades to cut the rib bones into short ingestible sections of lengths equal to the spacing between the saw blades.
