Help identifying symbol...

This silver cross pendant was purchased in Iceland by my father around 1974. He said when he bought it he was told that it symbolized something, but he can’t remember what.

I would love to know its meaning, and it’s name if it has one.

Photo of said pendant:

Looks alchemical to me, but it didn’t show up in any of alchemical books that I glanced through…

An interpretation of a Wolf-cross? Basically aThor’s hammer but post-Christianization… only done in more symbolic way.

I first thought of this (Helm of Awe) - this is bugging me now, know I used to know this (grrrrr…old age, sigh)

A wee bit down the page, you will find a similar piece, with the following description:

~ Repel Evil Rune Pendant, Pewter ~
“Galdrastafir”
Magical Icelandic Binding Runes
Runebind crafted to protect you from evil. The origin of this collection of binding tunes is in Icelandic magic and dates back to the middle ages. These magical runes called upon ancient gods and goddess to work their spells. Much of what we know about Icelandic magic has been translated from “The Galdrabok”. Wear them and fulfill your desires…

Thanks for your help guys, those last two are rather similar to it.

Let the ideas keep flowing!
