ABSTRACT:
An explosive device is disclosed, which is particularly suitable for high energy applications, e.g., priming blasting explosives, cutting cables and for secondary blasting. The device comprises an explosive material having an indentation upon a surface thereof. The indentation which has a mouth, is substantially symmetrical about an axis perpendicular to the mouth. The cross-sectional area of the mouth is at least as great as any other cross-sectional area, normal to the axis, within the indentation. The thickness of explosive surrounding the mouth is greater than the critical diameter of the explosive.
