ABSTRACT:
A burglar bar breaking tool comprises a solid block or tool head of relatively heavy metal having at least one slot extending lengthwise along part of its peripheral edge for receiving the end of a prying tool, and a recess extending inwardly from the peripheral edge of the block for engagement transversely over a burglar bar so that a prying tool or handle shaft engaged in the slot can be used to apply twisting force to the burglar bar. In one embodiment, the block periphery is four-sided and has sleeves welded to each of its four sides each defining a slot for receiving a prying tool. In another embodiment, the tool head is permanently secured to one end of a handle shaft.
