I believe a new weapon addition is in order.
Perhaps be called Knightly Claymore and base the appearance off the Knightly Arming Sword (obviously change it a little, the fact that Katana, Wakizashi and Nodachi are scaled versions of eachother sucks)?
Anyway, stats have been adjusted from Sword of War+Great Sword+Two Handed Sword so it is in now way overpowered.;
