Innovative and universally applicable puncher for all types of baitfish. The puncher was specifically developed by Stefan Seuss for use with effective dead-bait rigs. The sharp-edged, laterally beveled insertion tube penetrates the back of the baitfish with precision and, with a slight twist of the puncher, removes a piece of back fillet. In the resulting cavity of the baitfish, dead bait sticks or cork sticks can now be inserted, giving the dead bait a natural, horizontal buoyancy. In the current, the dead baitfish begins to swim very realistically, convincing every river catfish.
