A composite mystery to me.

[mariusgmioc]

Now a novice's oppinion:

The blade appears to be very old and the engravings don't add too much to the "commercial" aspect of the blade.

So, my guess is they are talismanic.

PS: I said that the blade APPEARS to be very old because I believe with this type of blades it is rather easy to age them and make them look ancient.
