How old are the katar types?

[Jens Nordlunde]

Ian,
In the book it say that it is a shortened European sword blade.
What I find interesting is, that even with dated blades you can not be quite sure, the dating was made when the katar was new, or sometime later, maybe 'helping' a bit on the age when dating it. But in this case we know for sure that the katars are, at least from the 17th century.
