  "claims": [
    "1. A system comprising: a special purpose stake, said special purpose stake is configured to be driven into the ground to support a foundation member or ancillary structure, in which said special purpose stake comprises: at least a shaft section; at least a head portion; and wherein said head portion comprises at least one or more extension sections; a special purpose stake removal apparatus having a principal member, in which said principal member comprises: a prying end; a first side; a second side; a handle end; and a handle contrivance; a first engagement member, said first engagement member comprises: at least a first impact surface; and a first lever contact surface; a second engagement member, said second engagement member comprises: at least a second impact surface; and a second lever contact surface; wherein said first impact surface is configured to contact said at least one or more stake head extension sections to remove a special purpose stake that is driven into the ground; wherein said second impact surface is configured to contact said at least one or more stake head extension sections to remove said special purpose stake that is driven into the ground; wherein said first lever contact surface is configured to contact said at least one or more stake head extension sections to remove said special purpose stake that is driven into the ground; in which said special purpose stake further comprises at least one of a T-shaped stake and a cross-shaped stake, and, wherein said first engagement member and said second engagement member are located on said first side of said principal member, and said handle contrivance being located only on said second side of said principal member.",
    "2. The apparatus according to claim 1, wherein said first engagement member and said second engagement member are located at said prying end and first side of said principal member.",
    "3. The apparatus according to claim 2, further comprising a handle contrivance connected transversely to said handle end and second side of said principal member, wherein said handle contrivance is at least partially cylindrical along its length, wherein said principal member is left with a straight section available for sliding contact with said cross-shaped stake and/or T-shaped stake.",
    "4. The apparatus according to claim 3, wherein said principal member further comprises two divergent members each having a free end and said handle contrivance spans the free ends of said two divergent members to define a peripherally closed passageway collectively formed by the two divergent members and the handle.",
    "5. The apparatus according to claim 1, in which said at least one or more extension sections of said T-shaped or cross-shaped stake comprise at least one or more angled portions.",
    "6. The apparatus according to claim 5, in which said first impact surface comprises a first wedged impact surface that is configured to engage at least one of said angled portions of said at least one or more extension sections of said T-shaped or cross-shaped stake.",
    "7. The apparatus according to claim 6, in which said second impact surface comprises a second wedged impact surface that is configured to engage said at least one of said angled portions of said at least one or more extension sections of said T-shaped or cross-shaped stake.",
    "8. The apparatus according to claim 7, further comprising an auxiliary handle.",
    "9. The apparatus according to claim 7, in which said stake implement further comprises at least one of a T-shaped stake and a cross-shaped stake, wherein said T-shaped or cross-shaped stake further comprises a round shaped upper and lower shaft.",
    "10. The apparatus according to claim 9, wherein said at least one or more extension sections are positioned about 2″ inches below a topmost end of said round shaped upper shaft where said round shaped upper shaft and round shaped lower shaft meets.",
    "11. The apparatus according to claim 7, wherein said cross-shaped stake further comprises a square shaped upper shaft and lower shaft.",
    "12. The apparatus according to claim 5, wherein said at least one or more extension sections are positioned about 2″ inches below a topmost end of said shaft section.",
    "13. The apparatus according to claim 5, wherein an angle of each of said at least one or more angled portions comprises approximately 15 degrees incline.",
    "14. The apparatus according to claim 13, wherein each of said at least one or more extension sections extends to around ⅜″ inch on both sides shaft section.",
    "15. The apparatus according to claim 1, wherein said first side is available for sliding contact with said at least one of said special purpose stake, whereby said principal member is operable to be accelerated on a generally straight line along said first side while sliding against said special purpose stake so that a significant impact is generated upon contact of said first engagement member and said second engagement member with said special purpose stake.",
    "16. A system comprising: means for supporting a foundation member or ancillary structure; means for prying or removing said foundation member or ancillary structure supporting means; a first engagement member; a second engagement member; a principal member disposed on said prying or removing means, in which said principal member having a first side and a second side; a handle contrivance; and wherein said first engagement member and said second engagement member are on said first side principal member, which said handle contrivance being located only on said second side of said principal member, and Wherein said first side is available for sliding contact with said at least one of special purpose stake, whereby said principal member is operable to be accelerated on a generally straight line along said first side while sliding against said supporting means so that a significant impact is generated upon contact of said first engagement member and said second engagement member with said supporting means.",
    "17. A system comprising: a stake implement, in which said stake implement comprises: at least a shaft section; at least a head portion; and wherein said head portion comprises at least one or more extension sections; a stake removal apparatus having a principal member, in which said principal member comprises: a first side; a second side; a handle end; and a handle contrivance a first engagement member, said first engagement member comprises: at least a first impact surface; and a first lever contact surface; a second engagement member, said second engagement member comprises: at least a second impact surface; and a second lever contact surface; wherein said first engagement member and said second engagement member are located on said first side of said principal member, and wherein said first side is available for siding contact with said at least one of said special purpose stake, whereby said principal member is operable to be accelerated on a generally straight line along said first side while sliding against said special purpose stake so that a significant impact is generated upon contact of said first engagement member and said second engagement member with said special purpose stake; wherein said first impact surface is configured to contact said at least one or more stake head extension sections; wherein said second impact surface is configured to contact said at least one or more stake head extension sections; wherein said first lever contact surface is configured to contact said at least one or more stake head extension sections; and wherein said handle contrivance is located only on said second side of the principal member.",
