It is said that William Wallace would "fence" with his sword. If you have ever seen it, you will notice that it has no secondary grip. EEP!

Must have been a STRONG fella.

As for a fencer vs a claymore or bastard sword swinging Scot, I would put money on the Scot. Yeah, he might get stuck 1 or 4 times, but that would only serve to piss him off something fierce.
