A pistol or musket can be considered elegant weapons, as cowboys in the Old West duelled and looked elegant and skilled. And muskets required a good working knowledge and tactics for a military to be good with them. The only elegant modern weapon seems to be a sniper rifle, as you have to take into account wind speed, direction, velocity of the bullet, etc.
Of course the most elegant weapon of all would be information, a person with information can make or break nations, all without a drop of blood spilt.
