Which tool is used for breaching locks or heavy doors?

• A. Halligan bar
• B. Sledgehammer
• C. Flathead axe
• D. Pry bar

Answer: (B)

When breaching locks or heavy doors, you rely on delivering high-force impact to defeat the door hardware and the door itself. The sledgehammer provides the mass and momentum needed to drive through or break apart thick jambs, hinges, and lock assemblies when leverage alone isn’t enough. It’s the tool that supplies the power behind a breach, especially on reinforced or solid doors. The Halligan bar is used for leverage, prying, and manipulating hardware, the pry bar serves a similar levering function, and the flathead axe is more about cutting or chopping. But for the heavy-duty bursts of force required to overcome a tough door, the sledgehammer is the go-to implement because of its ability to deliver direct, substantial blows.
