Well, swords are fun, they look cool, swords are fun, they cost a lot, they are fun and if they have real but non-sharpened edges, you can fight with 'em. Of course slowing the swing before the impact but anyways. And oh yeah, swords are fun!
And oh well, I have a nice curved dagger and a repro flintlock from Tunisia, a cool dagger from... Ahh, i think it was from Crete... Plus my 4 inch Python repro and a nice decorative katana.
They all have (well not sure about the daggers) such blades that if you tried to sharpen 'em, they wouldn't.
And as for the meaningfulness of this stuff, at least it's nice to have 'em hanging on my wall alongside with other "trophies" (such as some African handwork, Vietnamese hats etc.) and a world map.
