Weapons work primarily as deterrents that prevent fights rather than win them

Evidence

Because fighting is dangerous, males assess each other beforehand, comparing weapons and pushing. Claws function as deterrents, and fights only escalate when males are evenly matched. — Emlen, Douglas J, Animal Weapons_ The Evolution of Battle, 966
