The name Claymore is the Anglicised form of the Gaelic word, claidheah mòr meaning "great sword." There are many examples in various museums, but all have the distinctive pierced 'clover-leaf' (quatrefoil) finials to the quillons and wheel pommel.
Possibly used by William Wallace in the film with the wannabe-Aussie, Septic-sellout Mel Gibson. In reality - ie several light years from Gibson's political views - Wallace is highly unlikely to have used one.
Calling basket-hilted Scottish broadswords 'Claymores' is bone.
