thanks everyone for the very good comments, especially Mark/Reventlov for filling in the T ,N and A , sounds plausible to me and have indeed seen that T in this form before in a publication of a sword inscription.

so we have now ??DNIS(D or R?)TNEDA

I also made some pictures of the other side, not so easy.
I can't make much of it, there is only 1 cross visible of which one arm ends in a longer curved line instead of a small triangle, further 6 vertical parallel lines, 3 up and three down. a small circle.......
In the Netherlands, more often inscribed and broken 13th century swords or blades have been found I don't really have a theory yet as to why and what exactly the function of this "ceremony" has been.

best,
Jasper
