The invention comprises a device that uses a flexible material, preferably in a mostly square shape. An explosive charge, usually in the form of a sheet of explosives, is cut to fit on the top side of the flexible material. A cutting plate, having orthogonal grooves on the top, is placed under the flexible material. An initiating means is connected to the explosive charge so that upon initiation, the grooves focus the explosive charge so that the cutting plate forms a plurality of petals that press into a soft metal container to create a fragment-free opening in the soft metal target material.

1. A device for creating an opening in a target material, having a first hardness, comprising:a cutting plate, having a second hardness being greater than the first hardness, with orthogonal grooves on a front side wherein the orthogonal grooves cut through the cutting plate to divide the cutting pl
1. A device for creating an opening in a target material, having a first hardness, comprising:a cutting plate, having a second hardness being greater than the first hardness, with orthogonal grooves on a front side wherein the orthogonal grooves cut through the cutting plate to divide the cutting plate into four separate sections and an attaching means to attach the four separate sections together along the cut to reform the cutting plate;a sheet of material, having a third harness being less than the second hardness and having a surface area less than a surface area of the cutting plate and having a first and a second sides wherein the first side comprises a position against the front side of the cutting plate, placed upon the front side of the cutting plate with the orthogonal grooves; an explosive charge placed upon the sheet of material, positioned substantially along the orthogonal grooves, only on the second side of the sheet of material;initiating means, located proximately central to the explosive charge, to initiate the explosive charge, creating an explosive force that creates a plurality of petals cantilevered from the cutting plate that drive into the target material, creating a plurality of petals cantilevered from the target material to define a fragment-free opening in the target material.2. The device of claim 1, wherein the cutting plate comprises a substantially square shape.3. The device of claim 2, wherein the cutting plate comprises a steel based material.4. The device of claim 3, wherein the target material comprises an aluminum or steel based material.5. The device of claim 4, wherein the sheet of material comprises a polymer material.6. The device of claim 1, wherein the attaching means comprises tape.7. A method of creating an opening in an aluminum or steel based material, comprising the steps of:placing a first sheet of steel based material on the aluminum or steel based material, the first sheet having substantially orthogonal grooves on a side away from the aluminum or steel based material, wherein the orthogonal grooves cut through the first sheet to divide the first sheet into four separate sections and an attaching means to attach the four separate sections together along the cut to reform the first sheet; placing a second sheet, comprising a polymer material and having a surface area less than a surface area of the first sheet of steel based material and having a first and a second sides wherein the first side comprises a position against the front side of the first sheet, on the side of the first sheet on the grooves; placing an explosive charge on the second sheet, positioned in substantial alignment with the grooves, only on the second side of the second sheet; andinitiating the explosive charge to create a fragment-free opening in the aluminum or steel based material formed by edges of the sheet of steel based material punching through the aluminum or steel creating a plurality of petals cantilevered from the aluminum or steel based material.
