When you take the Attack action on your turn and attack with a Light weapon, you can make one extra attack as a Bonus Action later on the same turn. That extra attack must be made with a different Light weapon, and you don’t add your ability modifier to the extra attack’s damage unless that modifier is negative. For example, you can attack with a Shortsword in one hand and a Dagger in the other using the Attack action and a Bonus Action, but you don’t add your Strength or Dexterity modifier to the damage roll of the Bonus Action unless that modifier is negative.

iMprovisEd wEapons If you use an object—such as a table leg, frying pan, or bottle—as a makeshift weapon, see “Improvised Weapons” in “Rules Glossary.” Also see those rules if you wield a weapon in an unusual way, such as using a Ranged weapon to make a melee attack.
