Roman Scutum - This shield is made predominantly out of wood with additional wooden back bracing for added strength.

The curved shape of a scutum allowed it to absorb (and deal) heavy blows, while the sides sloped away from the attacker, allowing arrows and enemy blows to glance off without transmitting the full force of the impact to the legionary sheltering behind it. The boss in the centre of the shield (the umbo), constructed either from copper alloy (brass or bronze) or iron, was itself used offensively, being heavy and dense enough to stun or wind an opponent.
