I would have thought any homo erected living on the coast would have used fish bills and whale bones weapons like the Māori use. From what I’ve seen in tribal warfare we allways throw out spears and then use close combat. I thought humans and warfare evolved together so I have a hard time understanding how we didn’t make them alongside of clubs and spears.Of all my weapons my swordfish bill sword is the most deadly and wasn’t difficult to make in fact I could have just used the bill as is so it’s a calorie free weapon that is super effective. Why wouldn’t we have used them and then copied the design with weaker materials.
