Because, the sword belongs to Godric Gryffonder and it was made by a Goblin.
The sword only takes in only what makes it more stronger.
In chamber of secrets Harry killed a Bassilsk (Snake) with that sword, so it has its venom on it. Making the sword even more stronger.
Harry destroyed one of the Hocruxes (Tom Riddle's Dairy) with the Bassilsk (snake) frang, which has its venom.
Now with the venom on the sword, it will be helpful to destroy the Hocruxes.
That's the reason Dumbldore left the sword for Harry in his will.
Severus Snape.

No, though there is a scene where Harry strips down to his underwear before diving into the pond to retrieve Gryffindor's sword.
