Tethered

Source Treasure Vault pg. 222 1.1
This weapon is attached to a length of rope or chain that allows you to retrieve it after it has left your hand. If you have a free hand (including if you've just thrown a two-handed tethered weapon and have a hand holding nothing but the weapon's tether), you can use an Interact action to pull the weapon back into your grasp after you have thrown it as a ranged attack or after it has been disarmed (unless it is being held by another creature).
