Tungsten has gained a lot of popularity recently. Tungsten uses about 50% less space than lead for the same amount of weight. This means 1-ounce tungsten alloy fishing jigs have a smaller volume, letting it penetrate weeds easier.
Tungsten fishing sinkers are weight used in conjunction with a fishing lure or hook to increase its rate of sink, anchoring ability, and casting distance.
Nowadays, a popular approach to weighting down soft plastics is the advent of small tungsten nail sinkers to add small amounts of weight internally to soft plastic lures.
Tungsten worm weights, also called tungsten barrel weights in some countries, are known as "Diamond Series" because of they are drilled, beveled and diamond polished to avoid damaging the line.
