Abstract: A disposable sinker including a water soluble member for attachment to a fishing line. An extension on the soluble member protrudes downwardly and is embedded within a solid body of the sinker. The soluble member defines openings for line passage and for water entry to expedite dissolution and sinker separation. A wax coating protects the soluble member from premature disintegration. A pull tab is provided which is removable prior to sinker use to expose a portion of the soluble member. A reinforcing agent is applied to the soluble member to resist line imparted forces. A method of manufacture is also provided.
