Yep this thing is about 8 pounds and about sixteen inches tall. It has folding legs to act as a stand off. A shaped charge uses a copper cone that in concave and holds back the explosive from the target. Upon detonation the cone collapses forming a jet or thorn of molten metal that penetrates the target through a small opening created by the jet. Makes holes in stuff with high explosives! Inert and in my museum.
