Just keep using your sword in battles, the more you use it, the higher the mastery will get. Also, farming bosses helps a lot as they give good XP.
Actually, grinding sword mastery is overrated. Focus on leveling up your character first for better overall gameplay.
From personal experience, find an area with respawning NPCs close together. Use a sword with a good AOE attack, like Saber. Also, join a server with fewer players to avoid competition.
