An ancient knife design, sometimes called viking but actually much, much older. Variations can be found through history in many places, but the design spread to nordic countries during the viking era. It was an affordable household knife made from iron rather than steel and without frills, often called "woman's knife". Viking women carried scissors, small knives, keys etc. fastened in their chains they wore hanging not around the neck but fastened at the shoulders.
Smallish or medium size. Also available as pendant
(or earrings, get 2).
You will need to sharpen the knife yourself if desired, the printing and polishing process doesn't allow for such sharp edges.
