That's something I was thinking on, as weapons sometimes also contained what I would consider religious fetishes.
I don't remember if I saw it here on PF or elsewhere, but https://www.livescience.com/51802-me...scription.html
The River Witham sword was forged in Germany, which was then the blade-making center of Europe, according to the British Museum. And pre-Christian Germanic tribesman inscribed runes onto their swords, axes and armor to "endow the items with magical powers," the Fyris Swords Project researchers wrote in a paper published in the journal Waffen- und Kostümkunde (Weaponry and Costumes) in 2009.
It's possible that this ancient tradition was carried over to Christian times and that the inscriptions on the blades were therefore meant to "invoke God’s holy name and his grace to gain support and protection in battle," according to the researchers.I would assume the fetish/war club combinations were of a similar meaning to the owners within their own cultural trappings.The first two letters on the River Witham sword are ND, which van Hasselt said might be a kind of invocation that stands for "Nostrum Dominus (our Lord) or Nomine Domini (name of the Lord)."
The XOXcombination that follows could refer to the Holy Trinity of the Christian faith. And the two plus sign-shaped symbols before and after the inscription are likely Christian crosses, according to the Fyris Swords Project researchers.
