These larger more aggressive tools (aka Hooligan bars) are used by firefighters and demolition workers to open doors and windows.

Use as a Wedge or a Lever against a nearby fulcrum to cause or block movement. Also when a shaft is rusted into a tube and you need to crack the corrosion to lever it out.
