Claim 2:
3. A wireline cable cutting tool, comprising:
a housing system comprising a fishing neck and a wireline cable cutter at a housing system first end and a wireline connection housing at a housing system second end;
a mandrel system comprising a cutter press at a mandrel system first end and a wireline cable termination at a mandrel system second end;
a first triggering mechanism configured to communicate with the mandrel system;
a second triggering mechanism configured to communicate with the mandrel system;
a pressure piston assembly comprising a restrictor orifice and one or more check valves;
a first biasing element configured to communicate with the pressure piston assembly; and
a second biasing element configured to communicate with the second triggering mechanism;
wherein the pressure piston assembly is configured to communicate with the first triggering mechanism;, wherein the cutter press is configured to communicate with the wireline cable cutter;, having a wireline cable extending through an axially-centered channel of the fishing neck, cable cutter, and mandrel system and terminating at the wireline cable termination at the mandrel system second end;, wherein the second triggering mechanism is activated by a first tensile load applied to the wireline cable;, wherein the first triggering mechanism is activated by a second tensile load applied to the wireline cable;, wherein the second tensile load is greater than the first tensile load;, wherein the wireline cable cutter is activated by a third tensile load applied to the wireline cable; and, wherein the third tensile load is greater than the second tensile load; and, wherein the pressure piston assembly is configured to delay activation of the wireline cable cutter after the third tensile load has been applied to the wireline cable.
