Abstract: A firefighter's wrecking tool or pike pole includes a first elongated tubular pole section connected to a penetrating tip assembly at one end and to a second pole section at its opposite end. The second pole section supports a manually activated reciprocable piston hammer slidably mounted on the second pole section and engageable with spaced apart anvils secured to the tool for receiving repeated impact blows to facilitate use of the tool. The piston hammer may be locked in a position for carrying and manipulating the tool by a thumbscrew or by a sleeve type locking member.
