Well to me its a bit of inhuman strength, mixed with his magic making it lighter.
So long as his aura is on it he can control it. So its not that its heavy, its just within his dominion so it "floats"
If that makes sense.
If it doesn't ill change it. 5 swords in one would be heavy, but they were all shortswords. About 10-15pounds each.

Actually, most swords weigh well less than 10 pounds. Even 5ft Claymores only weighed around 6 pounds.
