A barbed or razor wire crossing apparatus and system that enable the safe passage for a user either over or between barbed or razor wire. Also a game carrying kit that enables a hunter to field dress an animal and to prevent or greatly limit the spread or exposure of the hunted game's blood during transportation.

Container (10) is generally cylindrical except for a longitudinal concave groove (11) extending along its entire length. Upon explosion, the contour of this groove (11) results in a focussing effect on the wall material due to the oblique angle at which the expanding cylindrical detonation wave front impacts upon its inner wall. This produces the forging of a rough rod-like projectile (11.sub.1) which, being coherent, maintains its velocity and consequently travels much further than the randomly shaped projectiles (10.sub.1).

A deployable, linear explosive structure includes a split tube, an explosive coupled to the split tube, and a fragmentable or non-fragmentable projectile disposed with respect to the explosive. The split tube can be rolled into a non-deployed state in which the split tube has a flat, rolled profile. The split tube also can be deployed from the non-deployed state to a deployed state in which the split tube is extended along its length and has a curved cross-section along its length. The split tube provides support of the explosive structure in the deployed state. The split tube also provides smaller storage and transportation volume for the explosive structure when rolled in the non-deployed state.
