hand groover is a tool specifically designed to
groove and flatten seams in sheet metal or similar materials. It is commonly used in metalworking, plumbing, and roofing applications to ensure that seams are properly shaped, grooved, and flattened for a tight fit, better strength, or enhanced aesthetics.
It is commonly used in sheet metal work, particularly in operations like joining or finishing seams in ducts, pipes, or roofing sheets.
A stake is a solid support tool used in sheet metal work, typically to assist in forming, bending, or shaping metal. It is not used to groove or flatten seams directly, though it may serve as a base during some operations.
