Patent ID: 8302534

Claim:
A shaped charge tubing cutter comprising a pair of substantially matched explosive units, each unit comprising a first explosive material that is formed intimately against a metallic liner, said liner being configured substantially about an axis of revolution, a first increment of said liner being configured substantially to the shape of a first conical frustum between a first normally truncated apex and a first normally truncated base, a second increment of said liner being configured substantially to the shape of a second conical frustum between a second normally truncated apex and a second normally truncated base, the truncated base of said first conical frustum being merged with the truncated apex of said second conical frustum, said first explosive material being substantially confined between said liner and a metallic end plate having a perimeter about said axis of revolution that substantially corresponds to a perimeter of said second truncated base, said units being joined coaxially at said first truncated apex with a first explosive material interface along a substantially common juncture plane.
