This very small shield is a favorite of duelists and quick, lightly armored warriors. It's typically made of steel and strapped to your forearm. You can Raise a Shield with your buckler as long as you have that hand free or are holding a light object that's not a weapon in that hand.
Using this shield
A shield grants its circumstance bonus to AC only while raised. Raising it costs 1 action, and the bonus lasts until your next turn starts. With the Shield Block reaction you can reduce damage by the shield's Hardness (3); the shield then takes the remaining damage, and it breaks at 3 damage and is destroyed at 6.
