Restoration work performed
This breaker bar was refreshed to be a working tool, not a mirror-polished showpiece: 1. Cleaning: Hand cleaned with WD-40 and 3M abrasive pads to remove shop grime and active surface rust while preserving the original finish and stampings. 2. Lubrication: Applied mineral oil and Hoppes at the flex joint and drive interfaces, then worked the head through its full range of motion. 3. Protection: Wiped back and finished with a thin coat of paste wax so the surface feels dry in the hand but has added rust resistance.
No sockets or accessories are included—breaker bar only.

- Heavy-duty breaker bar for vintage or modern mechanic’s work.
