OK. As I understand it the blades could typically have a family motto or some Latin quote on it. I guess it could have been abbreviated. I have a schiavona with a not too dissimilar blade which has half a Latin motto on each side of the blade.
Alternatively, I guess the text could represent a prayer like (I)N (N)OMINE...but not sure what MINI would stand for. It’s not a palindrome but not far off.
