Ok, somehow this has still been overlooked, or maybe you pay to not have a sheath and instead have a magical floating sword!

Summary
Ok, i'm biased here as i own a MW longsword and use it all the time, but the point stands. Why should i pay higher upkeep than someone using a weapon which is almost exactly the same? Realistically 1 length is about as useful as 0.2 weight, so why the higher price?
Paying for visuals or something?
