Circles or Rings typically represent eternity or the life cycle.
But, to me, this one appears to be holding something at it's center.
Something invisible, something tortured. Some poor trapped soul.
Could be part of a great Halloween cosume. Or, just wear it if that's your style.
It still looks cool. Even if I made it sound creepy.
It appears normal from the front. But, when you take look at the back.
There are more spikes inside.
They feel like they represent the internal struggle that is being human. As we hide ourselves from the world, this mace hides its spiked internals from the viewer. Only the wearer knows its true identity.
