In a pike pole used in fire rescue having a shaft that includes a first half and a second half, a handle connected to one end of the shaft that is located on the first half of the shaft, a longitudinal axis, and a cutting-piercing member connected to the other end of the shaft that is located on the second half of the shaft, said cutting-piercing member having a first element extending along the longitudinal axis and having a pointed tip that is located substantially on the longitudinal axis and that points in a direction that is parallel to the longitudinal axis, the improvement comprising:

an elongated cutting member pivotally connected to the first element and being controllably moveable between a first laterally-oriented position at which the cutting member includes an edge that is located along at least half a length of the cutting member, is oriented substantially perpendicular to the longitudinal axis, and extends further from the longitudinal axis than any other member on the second half of the shaft while forming an opened relationship with the first element, and a second longitudinally-oriented position at which the cutting member extends generally along the longitudinal axis and forming a closed relationship with the first element, the first laterally-oriented position of the cutting member enabling a thrusting and cutting of the pike pole through a building structure followed by a rotating and removal of the pike pole in order to remove portions of the building structure using the edge of the cutting member, and the second longitudinally-oriented position of the cutting member facilitating an extraction of the pike pole from the building structure in response to the edge of the cutting member preventing the removal of the pike pole from the building structure when the cutting member is in the first laterally-oriented position; and

a controlling system connected to the handle and being adjustable between a first position at which the cutting member is maintained at the cutting member first laterally-oriented position and in the opened relationship with the first element, and a second position at which the cutting member is released and pivotally moveable to the cutting member second longitudinally-oriented position and in the closed relationship with the first element;

wherein the controlling system comprises a lever arm pivotally connected to the handle and a pushing element extending between and pivotally connected to the lever arm and the cutting member, said pushing element being moveable towards the cutting member and away from the handle, in response to movement of the lever arm, between a first position at which the cutting member is maintained at the cutting member first laterally-oriented position forming the open relationship with the first element, and a second position at which the movement of the pushing element towards the cutting member and away from the handle moves the cutting member to the second longitudinally-oriented position in which the cutting member forms the closed relationship with the first element.

2. The pike pole, as set forth in claim 1, wherein the cutting member has a slot and the controlling system has a holding member, including:

a pulling element connected to the holding member and to the handle and forming an adjustable loop longitudinally extending beyond the handle, said holding member being moveable, in response to movement of the pulling element, between a first position at which the holding member is nested within the cutting member slot and a second position at which the holding member is spaced from the cutting member slot.

3. The pike pole, as set forth in claim 1, wherein the cutting member has a slot and the controlling system has

a holding member,

a lever arm pivotally connected to the handle, and

a pulling element extending between and connected to the lever arm and the holding member, said holding member being moveable, in response to movement of the lever arm, between a first position at which the holding member is nested within the cutting member slot and a second position at which the holding member is spaced from the cutting member slot.

4. The pike pole, as set forth in claim 3, including a loop element having first and second end portions, said first end portion being fixedly connected to the pike pole handle and the second end portion being adjustably connected to a buckle fixedly connected to the pike pole handle.

5. The pike pole, as set forth in claim 1, including a flexible loop element having first and second portions that are directly coupled to the pike pole handle- and that allow the flexible loop element and to be adjustable.

6. The pike pole, as set forth in claim 1, wherein the lever arm is of an angular configuration and the pushing element is connected to the lever arm at a spaced distance from the pivotal connection of the lever arm to the handle.

7. The pike pole, as set forth in claim 1, including a slot formed in the shaft adjacent the cutting-piercing member and said pushing element extending through said slot.

8. The pike pole, as set forth in claim 1, wherein said cutting member has an opening and the controlling member has a lever arm pivotally connected to the handle,

a leaf spring connected to the first element and extending over the cutting member opening,

a holding member connected to the leaf spring and being extendable into the cutting member opening,

a wedge having a longitudinal axis, first and second portions and a slot formed along said axis, said slot being of a size sufficient for receiving said holding member, and

a push rod connected to the wedge and to the lever arm, said wedge being slidably moveable, in response to movement of the lever arm, between a first position at which a lesser portion of said wedge is positioned between the leaf spring and the cutting member and the holding member is positioned within said cutting member opening and a second position at which a greater portion of said wedge is position between said leaf spring and the cutting member, said leaf spring is positioned away from said cutting member and said holding member is cleared from said cutting member opening.

9. The pike pole, as set forth in claim 8, including a loop element having first and second end portions, said first end portion being fixedly connected to the pike pole handle and the second end being adjustably connected to a buckle fixedly connected to the pike pole handle.

10. The pike pole, as set forth in claim 1, wherein the controlling system includes a rotatable handle and an actuating rod connected to the handle and being telescopically moveable relative to the handle in directions toward and from the cutting-piercing member in response to rotation of the handle.

11. The pike pole, as set forth in claim 10, including a loop element having first and second end portions, said first end portion being fixedly connected to the pike pole handle and the second end portion being adjustably connected to a buckle fixedly connected to the pike pole handle.

12. The pike pole, as set forth in claim 1, wherein at least one of the handle and the shaft is designed to conceal at least a portion of the controlling system.

13. The pike pole, as set forth in claim 1, wherein a portion of the controlling system is designed to be at least partially concealed within at least one of the handle and the shaft.

14. The pike pole, as set forth in claim 1, wherein at least one of the lever arm and the pushing element is at least partially concealed within at least one of the handle and the shaft.

15. The pike pole, as set forth in claim 1, wherein the controlling system is coupled externally to the pike pole.

16. The pike pole, as set forth in claim 15, wherein the pushing element comprises a push rod, the push rod slidably coupled along an exterior surface of the shaft, and the lever arm pivotally coupled to an exterior surface of the handle.
