In 1990, archaeologists excavating a craftsman's workshop at Trendgården in northern Jutland uncovered a small soapstone mold from the late 10th century. It was carved to cast two different pendants from the same block: a crucifix on one side, a hammer on the other. Whoever ordered jewelry from that workshop could walk away wearing whichever god suited the day — or, if they weren't ready to choose, both.
The hammer was Mjölnir, Thor's weapon, and Thor was Asgard's default line of defense against the giants who wanted the nine worlds destroyed. Norse myth says the hammer was forged by two dwarven brothers, Sindri and Brokkr, and that Loki — mid-sabotage as usual — cost it its handle length by turning himself into a fly and biting the smith at the worst possible moment. Even short-handled, Mjölnir never missed and always flew back to Thor's hand, which is exactly the promise its wearers wanted strapped around their neck.

By the mid-900s, missionaries were baptizing Danish kings and hammer pendants were turning up in graves next to cross pendants, sometimes on the same body. Historians read this less as confusion and more as insurance: Harald Bluetooth's own conversion didn't happen overnight for most of his subjects, and a hammer around the neck was cheap protection to keep wearing while everyone worked out which religion was actually going to stick.
Hammer amulets have surfaced from Iceland to Russia, wherever Viking trade routes ran, which tells its own story about how far a piece of jewelry could travel as both fashion and faith. The pendant here is cast from an original found in Mandemarke on Møn, Denmark, dated to around the year 1000 — the same window as the Trendgården mold. It's sterling silver, available in two sizes and in a gilded finish, and it's a far more literal read of "hedge your bets" than most jewelry gets to be.
