Mjölnir, Thor’s Hammer, Hallows (makes me Holy) and Protects me.
(Is akin to a crucifix for a catholic kristin.)
Ægishjálmur, Helm of Awe, Protects me.
(Is akin to a St. Michael’s medallion for a roman catholic kristin.)
I always wear Mjölnir everyday and for blót.
I wear Ægishjálmur when I travel.
