Abstract
A safety fishing line release includes a first arm, a second arm, a spring, a first frictional pad, a second frictional pad, and a peg. The first arm has a tab opening at a first end which is sized to loosely receive a tab disposed at a first end of the second arm. The first and second frictional pads are fastened to the second ends of the first and second arms, respectively. A peg extends outward perpendicularly from the second frictional pad. A spring is inserted between the first and second arms, the spring forces the first frictional pad against the second frictional pad. A second safety feature utilizes a first and second prong to retain the fishing line instead of the peg or in combination with thereof. The safety fishing line release may be further improved by adding a force adjustment device. A second preferred embodiment of the safety fishing line release utilizes a force adjustment device and a simpler design. All safety fishing line releases which have cam assemblies may be called cam operated fishing line releases.
