Are there any magic weapons that return when thrown?

Question

As someone who's ended up throwing quite a lot of daggers at enemies, it would be nice to find one that magically comes back to me, so I don't have to worry about retrieving them or running out.

I know there's the returning weapon artificer infusion, but without an artificer in the party, it may be difficult to acquire one of those. I've also seen the bracer of flying daggers, but that's a Rare item (I imagine mostly because it lets you attack twice per action).

Are there any other ways to have a dagger, or other item with the Thrown property, magically return after I throw it?

Answer 1

Dwarven Thrower

There is at least one weapon that returns when thrown in the DMG (p. 167), the Dwarven Thrower.

DWARVEN THROWER Weapon (warhammer), very rare (requires attunement by a dwarf) You gain a +3 bonus to attack and damage rolls made with this magic weapon. It has the thrown property with a normal range of 20 feet and a long range of 60 feet. When you hit with a ranged attack using this weapon, it deals an extra ld8 damage or, if the target is a giant, 2d8 damage. Immediately after the attack, the weapon flies back to your hand.

This weapon has been in the game since the original brown books D&D. However, it requires you to be a dwarf; and it is very rare, even more rare than the Bracers of Flying Daggers you already identified as a possible solution.

As an alternative, you could also consider to take three levels in the Fighter (Eldrich Knight) class, and gain the Weapon Bond feature, that allows you to bond any weapon and gain this ability with it:

If it is on the same plane of existence, you can summon that weapon as a bonus action on your turn, causing it to teleport instantly to your hand.

Answer 2

May be a little late but there is the Weapon Bond Feature of the Eldritch Knight:

Weapon Bond At 3rd level, you learn a ritual that creates a magical bond between yourself and one weapon. You perform the ritual over the course of 1 hour, which can be done during a short rest. The weapon must be within your reach throughout the ritual, at the conclusion of which you touch the weapon and forge the bond.

Once you have bonded a weapon to yourself, you can't be disarmed of that weapon unless you are incapacitated. If it is on the same plane of existence, you can summon that weapon as a bonus action on your turn, causing it to teleport instantly to your hand.

You can have up to two bonded weapons, but can summon only one at a time with your bonus action. If you attempt to bond with a third weapon, you must break the bond with one of the other two.
