In the first year it came out, it was nicknamed "THE THREE-HEADED MONSTER", a truly appropriate name given there was three ways this casting sinker could be used.
1. Using the stainless steel spikes secured by the brass screw; it offers unrivalled grip.
2. Using the plastic star held by the brass screw, it provided medium grip.
3. Using the small plastic screw, you get the classic sinker. The spikes that keep the sinker anchored to the bottom, release automatically when the anchored line is given a sharp jerk.
