The runes used by Tolkien was the Germanic (please correct me if I'm wrong) ones although he called them Angerthas. In their time of use, the Shamans and Stonewriters (don't know the correct english word here, sorry...) of the North where treated as powerful wizards, and therefore striking fear into their enemies hearts. I doubt there is no other power in them, but in Tolkien's Middle-Earth everything is possible...
If you are interested in this debate, I advice you to study magic and magical history for some more years. Especially the parts covering the use of magical writing - hieroglyphs, runes and so forth.
We can only speculate, but it would be reasonable to believe that the writings was in the classical style of the runes engraved in the viking swords. This could be everything from old sayings to the name of the owner, so I don't think it's possible to get some real answers for your question.
