>>8265864>strong physical impacts with physical implementsIf we're talking logic, then all swords would be energy, and solid metal would be reserved for bludgeoning weapons only. If Cybertronians DID have a metal they could forge into weapons sharp enough to cut their own bodies presumably at least as well as energy, I suppose it would just come down to cost-effectiveness. Or maybe energy blades cut better but are too expensive/resource-intensive to equip every troop with one, so they rely on metal.
