I guess this is a bit old, but if you're still interested, there's one in Leeds Royal Armories - long sword (claymore-length-ish) with a wider blade for about the last quarter - about twice the width of the rest of the blade - clearly for hacking rather than thrusting.
- I can't find a link, but maybe the page will load later/they would answer a request for info? Also sorry for lack of technical info - I just remeber seeing it once!
