A fishing sinker assembly is provided including a weighted body and an elongated insert. The weighted body includes a throughbore defining a cavity extending between two openings. The elongated insert extends through the cavity and includes a proximal end, a distal end, and a middle portion. The proximal end includes a connecting means for connecting the fishing sinker to a fishing line. The distal end is larger than the size of at least one of the openings, wherein the distal end prevents the body from being slidably removed over the distal end. The middle potion includes a breakaway segment positioned within the cavity. The breakaway segment has a tensile strength less than that of the proximal end, distal end and fishing line attached to the proximal end such that added tension will cause the breakaway segment to selectively break prior to breaking of the proximal end, distal end or fishing line.
