Abstract: An apparatus for cutting frozen fish bait comprising a cutting head having a plurality of spaced-apart cutting blades (50) which are slidably moved between a stack of spacer blocks (26). The blocks include openings (42) to define a tunnel extending from top to bottom of the stack. The blades (50) have a retracted position and an extended position moving across the tunnel. A bottom gate (124) holds its frozen bait in the tunnel until the blades have sliced the bait into pieces. A fluid actuated cylinder (80) and piston 78 are attached to a blade mounting member (60) to provide the cutting power. A cycling valve (94), reversing valve (100) and actuator mechanism (110) provide operator control of the devices contained in housing (12).
