You find 1d6 (or a number up to 6 determined by your DM) shortswords with dark hilts on a thick bandolier that can be adjusted to fit around the chest or waist. You must spend a short rest with each sword to attune with it, but if you attune with at least one of these swords the remaining swords do not require an attunement slot.

In addition to being able to use each of these swords as a typical shortsword, as an attack action you can throw a sword into the air or at a target creature. If you are able to make multiple attacks this replaces one of them.
If you throw a sword into the air it orbits you at arm’s length for up to 1 hour, waiting for you to command it.

If you throw one of these swords at a creature, or as an attack action command a sword already orbiting you to attack a creature, it flies at the target avoiding cover and obstacles. Target creatures must be visible to you and within 30 feet. If you are able to make multiple attacks this replaces one of them. When you make an attack with these swords in either of these ways make an attack roll with proficiency and your Strength or Intelligence modifier. On a hit it deals 1d6 + your Strength or Intelligence modifier magical Slashing damage.
After an hour, when you dismiss it, or after it attacks a target, any sword still orbiting you will fly to your hand if you have a free hand, return to the bandolier if you are wearing it, or stab itself into the ground at your feet.
