A firefighting tool having a flat blade with a pointed leading end for piercing through structural panels, a plurality of stop teeth members for engaging a structural panel that has been pierced to defeat facile withdrawal of the tool, and a plurality of rip teeth members for sawing through the panels when the tool is reciprocated along its longitudinal axis. The stop teeth members are positioned at an angle relative to the rip teeth members and allow the firefighter to easily maintain the tool in an overhead configuration when it is used to remove ceiling panels because the angle of the stop teeth members results in a hooking action so that the ceiling supports the weight of the tool to some extent. Since the stop teeth members defeat inadvertent withdrawal of the blade, the firefighter need not make multiple penetrations of the ceiling panels or other structural member being removed by the tool.
