Lightsaber is basically a glow stick
Samurai swords are too thin
Highland claymore is too heavy
So I would go with Atlantan sword and the Viking short sword
Actually if you look into the old texts and the meaning of "claymore"in Scottish gaelic the claymore was most likely what's now called the Scottish broadsword
Interesting. This claymore is a 'highlander claymore' like the ones in Highlander or Braveheart. While not necessary historically accurate, it represents a popular style of giant sword in video games/ movies & military RP.
