Swords aren't heavy. most weigh 2-3 lbs. and 2-handers only wheigh up to 6. Secondly, they are balanced, so you could throw them, but then you would lose a big sharp sword throwing knives (which I own and can use well) are usually either all metal, or have a cord wrapped grip, the end left exposed. third, there are double ended throwers you can get, and there are some very large ones to boot (2 pounders!) and last but not least, throwing stars will veer off to the sides at any distance greater than about 5 meters unless they are weightedand you are damn good with them. I think a large (12 inch blade) fixed bladed knife that's well balanced would be the best bet if you don't want to lug a gun around in plain view.
