An apparatus for removing O-rings from a device is disclosed. The apparatus includes a first actuator assembly that is adapted to modulate at least two first cutting members via at least two pistons. The apparatus includes a second actuator assembly that is adapted to modulate at least two second cutting member via at least two pistons. The apparatus further includes a receiver module sandwiched between the first actuator assembly and the second actuator assembly. The receiver module is adapted to secure the device to remove the O-rings. The receiver module is adapted to be replaced according to a model of the device. The at least two first cutting members and the at least two second cutting members operate in a complementary manner and in synchronization with each other to perform at least two hitting strokes per cycle for an efficient breakage of the O-rings.

The present invention provides methods and apparatus for efficiently removing fish from gill nets and consistently initiating the bleeding process by providing electronic units having a flat outer surface with a sensor thereon, and a piston-actuated blade mounted behind an opening in the surface adjacent to the sensor. Electronics are provided to receive signals from the sensor and to operate the piston. In operation, a fish entangled in a gill net is brought near the sensor along the flat surface such that the fish gill is near the blade opening. Upon sensing the fish, the piston is actuated causing the blade to briefly extend through the opening in the surface in order to simultaneously cut the net and also punch into the gill of the fish, and then quickly retract. This action cuts the fish free from the net with minimal damage to the net, and also initiates the bleeding process.

In a round blade for slicing, a plurality of blade surfaces each having an arc shape and centered on a rotation center of a round blade main body are disposed to be spaced apart from each other on an outer peripheral portion of the round blade main body. A non-blade surface portion is disposed between the adjacent blade surfaces on an outer peripheral portion of the round blade main body. An outer end portion of the non-blade surface portion in a radial direction is located radially inward with respect to an outer end portion of the blade surface in the radial direction.
