From the perspective of geomantic omen, the sword is an object with special symbolic significance. In traditional culture, the sword is regarded as a sacred weapon, which can protect its holder from evil spirits. However, this statement lacks scientific basis and should not be regarded as a factor that determines fate.
Therefore, accepting other people's swords can't bring any special benefits or disadvantages. If you are interested in the sword, you can learn about the culture and history of the sword, but don't be overly superstitious about the symbolic meaning of the sword.
