I also got a strange feeling that this is not pure Latin.
And the above part of the blade reads the same on both sides:
il iusto uowe hic
sian ponito amia
The N and H are unclear at certain point because they are both 5 "dots" and there are also a few unknown symbols like ic (beeing one symbol instead of two) etc.
Good fun to research so i am very curious to see the results of that paper
