Jens Hansen The Ringmaker
The Oath Key with Infinity Bale, Yellow Gold
The heaviest of the three Ringmaker's Keys. A miniature of our Movie Ring forms the bow, the shank is cut with runes, and the bit is worked to look like woven iron.
In the Viking Age, oath rings were sworn on to bind legal, sacred, and personal vows under the eyes of the gods. We made this key with that in mind: solid and weighty, built to hold a promise.
Engrave the ring with your vow, two names and a date, or leave it blank until you know what it should say.
Cast in solid gold and finished by hand in Nelson, New Zealand.
