Viking Saxes with Drop Points (Museum Photos)

It seems that there are a great many people who think that a "Viking" knife had to have a sheepsfoot/wharncliff type point.  From my research, this blade style seems to have been found mainly in England, which leads me to the conclusion that the type of blade associated with Scandinavians warriors are in fact Anglo-Saxon in origin.

Here are a few photographs from museum collections in Norway: http://www.unimus.no/arkeologi/#/collectionView?
