The demolition tool is useful for, among other things, firefighters. The tool may be used to puncture a ceiling or other structure and to remove the ceiling material with the aid of the movable talons. The movable talons will automatically disengage if they hit an obstruction. The movable talons can be manually disengaged to prevent the tool from getting stuck in the ceiling or other structure. ## Claims ### Claim 1 A demolition tool comprising: a head assembly having a tip, a plurality of blades, and one or more movable talons, a handle shaft connected to said head assembly, and a handle end. ### Claim 2 (depends on 1) A demolition tool according to claim 1 wherein said handle end includes hammer end and/or pry bar. ### Claim 3 (depends on 1) A demolition tool according to claim 1 wherein said demolition tool includes a means for engaging and disengaging said one or more talons comprising a rotatable and slidable collar, a rod extending through said handle shaft and piston means that is connected to said one or more movable talons, all constructed and arranged to engage and disengage said talons. ### Claim 4 (depends on 3) A demolition tool according to claim 3 wherein said piston means comprises a piston rod having a gear member constructed and arranged for engaging a corresponding gear member on said one or more talons. ### Claim 5 (depends on 3) A demolition tool according to claim 3 wherein said handle end includes an actuating means constructed and arranged to cooperate with said rotatable and slidable collar. ### Claim 6 (depends on 1) A demolition tool according to claim 1 comprising means for said one or more movable talons to move from an engaged position to a disengaged position when said one or more movable talons engages an obstruction when in use. ### Claim 7 (depends on 1) A demolition tool according to claim 1 wherein said plurality of blades comprises three blades and wherein said one or more talons comprises three talons. ### Claim 8 A demolition tool comprising: a head assembly having a puncturing member, a plurality of blades and one or more movable talons, a handle shaft connected to said head assembly, a handle end, and a means for engaging and disengaging said one or more talons. ### Claim 9 (depends on 8) A demolition tool according to claim 8 wherein said means for engaging and disengaging said one or more talons comprises at said handle end a rotatable and slidable collar, a rod extending through said handle shaft and a piston means that is connected to said one or more movable talons, all constructed and arranged to engage and disengage said talons. ### Claim 10 (depends on 9) A demolition tool according to claim 9 wherein said piston means comprises a piston rod having a gear member constructed and arranged for engaging a corresponding gear member on said one or more talons. ### Claim 11 (depends on 9) A demolition tool according to claim 9 wherein said handle end includes an actuating means constructed and arranged to cooperate with said rotatable and slidable collar. ### Claim 12 (depends on 11) A demolition tool according to claim 11 wherein said actuating means comprises a sleeve having a track means and notch members. ### Claim 13 (depends on 8) A demolition tool according to claim 8 and wherein said handle end further comprises a hammer end and/or pry bar end. ### Claim 14 (depends on 8) A demolition tool according to claim 8 further comprising means for said one or more movable talons to move from an engaged position to a disengaged position when said one or more movable talons engages an obstruction when in use. ### Claim 15 (depends on 8) A demolition tool according to claim 8 wherein said puncturing member comprises a tip member and a plurality of blades. ### Claim 16 A demolition tool comprising: a head member having a puncturing member, a handle shaft connected to said head member, and a handle end comprising a hammer end, a pry bar end, and a member connecting said hammer end and said pry bar end wherein said member has a top surface, a bottom surface and side wall surfaces, said top surface, said bottom surface and said side wall surfaces being substantially smooth to allow gripping of said member of said handle end.
