1. An improved impact scraping tool for scraping material from surfaces, comprising:

  • (a) A ramming member having a longitudinal axis for transmitting thrust faces externally applied to said ramming member to said surface;

    (b) A thrust member telescopically mounted to said ramming member to permit slidable axial movement relative thereto;

    (c) Barrier means carried by said ramming member for barring further axial movement of said ramming member relative to said thrust member such that the momentum of said ramming member is transferred to said thrust member upon said thrust member engaging said barrier means;

    (d) a blade support plate carried by said thrust member having a laterally extending groove in its upper and under surfaces;

    (e) A pair of clamp members having a laterally extending shoulder adapted for insertion into said lateral grooves where said clamp members are mounted to said thrust member; and

    (f) A cutting blade removably mounted to said blade support plate such that upon application of an external thrust force to said ramming member said thrust member will engage said barrier means where upon the momentum of said ramming member is transferred to said thrust member thereby permitting said cutting blade to impact against said material surface.
