That's a lovely example. Thanks for sharing.
May general view on talismanic inscriptions is that no, they cannot really be truly translated. While we do see repetition of various magickal sigils on blades like this the final intention is always going to be both personal and secret. We can only ever assume what the original intentions were and frankly i don't really sure it is our right as collectors to "discover" the inner workings of such personal magick.
