The swords of the Osterburken-Kemathen type, a typology used by the Germanic and Roman warriors during the Migration Period, was not so different in its basic shape from the late Roman Illerup-Whyl specimens, of which they were maybe a further development. The Osterburken seems to be a bigger and heavier sword of Illerup-Whyl type. On the basis of the proportion and shape of the tip, these swords are therefore considered by Miks to be a hybrid evolution of the Straubing-Nydam type, but with strong elements typical of the Lauriacum-Hromowka type, both evident in the Illerup-Whyl swords.
