That's not even an argument. Please leave now, thanks.
Apart from what he said afterwards was an argument.
The type of claymores seen in computer games are not balanced for one-handed combat, you'd never be able to wield them effectively in dual-wield, despite what you might have seen in Neverwinter Nights. Even the typical long sword can be hard to use effectively with one hand (tho possible), the large scottish two-handed claymore is called two-handed for a very specific reason... the other types of one-handed claymores would not reach the size of claymores that were say in Oblivion or that people think of when playing games. To put it in perspective when talking about holding a claymore, you have to remember the sword is likely to be almost as long as you, only a Zweih?nder would likely be longer. So it's not so much an issue of overall physical strength but the strength to hold the unbalanced weapon what would place most of the strain on your wrist... good luck not shattering your wrist from the continued strain of dual wielding claymores.
