Messer has a knife hilt, shape and profile. Falchion has a sword hilt and a large knife profile blade.
The single edge viking sword has a sword hilt, sword blade profile type, sword length and is in every way a sword. Just a single edge. Even some with the same fuller as the double edge counterparts. They existed and were used at the same time. They are virtually identical aside from the aforementioned single edge...you are simply wrong. And apparently kind of soft in the head.
