Exemplary embodiments of apparatus and methods for remotely and explosively cutting the casing of a UXO and separating the fuzing components from the main charge in the UXO. A remote explosive separation tool creates a Linear Explosively Formed Projectile (LEFP) charge to separate fuzing components from live explosive threats in UXO, for example only, a 155 mm artillery round.
