A tool to prevent threads from been unraveling

Finishing with a whip finisher makes the fly more robust.
Rotate it back and forth 5 times before use.
A convenient magnet for picking up the hook is attached to the grip end.

Electropolishing is applied to the finisher part. The thread slides better and you don’t feel stress when turning or pulling out the finisher.
A neodymium magnet is attached to the grip end. Very useful when picking up hooks.
