I wrote quite recently about how I like Thor’s Hammer/Mjölnir pendants but don’t wear them because they have been co-opted by certain factions of the white supremacist movement.
I don’t normally subscribe to any secret social passports such as the meaning behind the colour of your shoelaces, whether you have a bandana in your back pocket, or which ear has an earring. I have, however, translated several research papers about Viking symbols being co-opted by white supremacists, and I really don’t want to send ANY signals of that kind to anyone. Not even accidentally. For the same reason I would never wear any Buddhist, Indian or Ethiopian symbols that resemble the swastika, even though the symbol was very commonly used thousands of years prior to World War II.
Having said that, though, I found this solid silver hammer pendant at a flea market recently. I initially decided not to buy it but it was so cheaply priced and vaguely shaped that I returned later the same day. I am not sure I am going to wear it anytime soon, but the handwork is beautiful.
