The spoke bomb is a weaponizable tool used in rescue operations.
It consists of supercompressed constructs of interconnected tritanium pins encased in an isolated chamber, with a small discharger set at their center. When a spoke ruptures and the tritanium comes into contact with air (or the encased backup pocket of oxygen contained within the bomb), it expands violently, blowing away anything in its immediate vicinity. The tritanium spokes click into place and form a complex prismic polyhedron, similar to a hubless wheel. The spokes are perfectly balanced, and effectively create a hole in a wall through which a person can pass.
It should be noted that they are not biased in operation, and will not distinguish between a hole created in a wall, a crumbling piece of metal wreckage, or someone's torso.
